From a microbiological aspect, oxygen encourages the growth of aerobic spoilage microorganisms. Therefore, the reduction of oxygen and its replacement with other gases can reduce or delay oxidation reactions and microbiological spoilage. Oxygen scavengers may also be used to reduce browning due to lipid oxidation by halting the auto-oxidative chemical process. The modification process generally lowers the amount of oxygen (O2) in the headspace of the package.

Direct microbiological techniques are the ultimate measurement of pathogen contamination, but these are costly and time- consuming, which means that products have a reduced shelf-life by the time pasteurization is verified. As a result of the unsuitability of microbiological techniques, milk pasteurization efficacy is typically monitored by checking for the presence of alkaline phosphatase, which is denatured by pasteurization. Destruction of alkaline phosphatase ensures the destruction of common milk pathogens. Therefore, the presence of alkaline phosphatase is an ideal indicator of pasteurization efficacy.

Pasteur had discovered that bacteria can ferment sugars into lactic acid, and another Frenchman, Emil Magitot, showed that fermentation of sugars could dissolve teeth in the laboratory. Bacteria had been observed inside carious dentin by Underwood and Miles in 1881, and these researchers also proposed that bacterial acids were necessary for removing the mineral of teeth. It was against this background that Miller developed his oral microbiological research, soon becoming appointed Professor of Operative Dentistry at the University of Berlin. He worked in the microbiological laboratory of Robert Koch in Berlin and began numerous research projects that introduced modern biological principles to dentistry.

A third species, A. skirrowii, has also recently been isolated from a patient with chronic diarrhea. Although the microbiological and clinical features of Arcobacter are not yet well defined, initial studies of A. butzleri suggest that these bacteria display similar microbiological and clinical features as C. jejuni, but are more associated with a persistent, watery diarrhea than with the bloody diarrhea associated with C. jejuni. Recent studies suggest that A. butzleri induces epithelial barrier dysfunction by changes in tight junction proteins and induction of epithelial apoptosis. Based on this model, the virulence of A. butzleri seems to have two phases.

On 1 April 2005, the Agency became a non-departmental public body, with the National Radiological Protection Board (NRPB) being merged into the organisation at the same time. 240px The origins of the HPA's largest facility in Porton Down can be traced back to 1940, when Porton had a highly secret and independent 'Biology Department' under the Ministry of Defence to study biological warfare and defence against it. It was called the 'Microbiological Research Department' (by 1946), and subsequently the 'Microbiological Research Establishment' (from 1951) with research becoming increasingly defensive and civilian in nature.

The dental plaque biofilm can result in the disease dental caries if it is allowed to develop over time. An ecologic shift away from balanced populations within the dental biofilm is driven by certain (cariogenic) microbiological populations beginning to dominate when the environment favours them. The shift to an acidogenic, aciduric, and cariogenic microbiological population develops and is maintained by frequent consumption of fermentable dietary carbohydrate. The resulting activity shift in the biofilm (and resulting acid production within the biofilm, at the tooth surface) is associated with an imbalance between demineralization and remineralisation leading to net mineral loss within dental hard tissues (enamel and then dentin), the sign and symptom being a carious lesion.

The remaining directors took the decision to put the company in a trust where 50% was shared with the employees and the other 50% in a charitable trust. In the 1960s demand for sterilized surgical blades increased and Swann- Morton developed, with the expertise of The United Kingdom Atomic Energy Authority at Wantage, a sterilisation process using cobalt-60 gamma radiation. It was one of the first commercial plants of its kind in the world and enabled Swann-Morton to be completely self-sufficient for all its sterilisation requirements. Today the irradiation and microbiological facilities are offered under contract to other healthcare manufacturers from Swann-Morton (Services) Limited and Swann-Morton (Microbiological Laboratory Services) Limited.

Snell is widely recognized as one of the foremost nutritional biochemists of the 20th century. His early work developing microbiological assays for key nutrients has been credited with facilitating the discovery of at least half of known vitamins due to their ease of use compared to more traditional animal studies. His 1939 publication describing a microbiological assay for riboflavin – then one of just two B vitamins known – is considered the first widely used such assay. His notable discoveries using these methods include the discovery and naming of folic acid, which Herschel K. Mitchell, Snell, and Roger J. Williams isolated from four tons of processed spinach and demonstrated to be a growth factor for the experimental organism Streptococcus faecalis.

This area of research seeks to provide a complete and efficient response to the problems and challenges related to water quality, particularly in the Mediterranean area. The assessment of water quality as it is defined in this area—considering chemical, microbiological, and ecotoxicological quality—allows identification of the tools needed for the adequate management and preservation of water bodies. The main objective of this area is to define the concentrations, fate and mechanisms of action of pollutants and pathogenic elements in natural and reused waters. The most modern chemical, microbiological, and ecotoxicological analytical methods are being implemented to assess water quality and to examine the corresponding characteristics of surface waters, groundwaters, and treated water, the latter including both drinking and wastewater.

A limited number of treatment options exist, including regular application of Capsaicin cream and prolonged relief may be provided by botulinum toxin treatment. Chromogenic pigments produced by bacteria (Corynebacterium in particular) are implicated in this condition but their exact role still requires careful microbiological elucidation. Chromhidrosis of the eccrine glands is rare, it occurs mainly after the ingestion of certain dyes or drugs.

Chromogenic microbiological media use colored enzymes to detect the presence of certain bacteria. In conventional bacteria culturing, bacteria are allowed to grow on a medium that supports many strains. Since it is hard to isolate bacteria, many cultures of different bacteria are able to form. To identify a particular bacteria culture, scientists must identify it using only its physical characteristics.

During the growing season, the inter-row spaces are hoed two to four times and the rows are weeded to conserve moisture and improve aeration. As a result, the soil’s microbiological activity increases and mobilization of nutrients is intensified. Row crops are valuable precursors of spring grain crops, flax, and hemp. The beneficial effect of row crops extends to the second crop.

The rate of microbiological activity slows during the last phase of waste decomposition as the supply of nutrients limits the chemical reactions, e.g. as bioavailable phosphorus becomes increasingly scarce. CH4 production almost completely disappears, with O2 and oxidized species gradually reappearing in the gas wells as O2 permeates downwardly from the troposphere. This transforms the oxidation–reduction potential (ORP) in the leachate toward oxidative processes.

S. maltophilia frequently co-occurs and forms multispecies biofilms with Pseudomonas aeruginosa. S. maltophilia substantially influences the architecture of P. aeruginosa structures, causing development of extended filaments. These changes arise due to diffusible signalling factor encoded by S. maltophilia. The growth of S. maltophilia in microbiological cultures of respiratory or urinary specimens is difficult to interpret due to its low pathogenicity, and not a proof of infection.

Some debate exists surrounding the exact cause of whiting events. And although much research exists on the subject, there is still no definitive consensus on the chemical mechanisms behind it. The three most common suggested causes for the phenomenon are: microbiological processes, re-suspension of marine or bottom sediments, and spontaneous direct precipitation from water. Of these three, the last has been ruled unlikely due to the unfavorable reaction kinetics of spontaneous calcium carbonate precipitation.

Traditional methods for detecting contamination in water, though highly accurate and sensitive, pose a number of obstacles. They are often costly, require the operation of a trained technician, and are labor intensive. They can also be time consuming, for example, microbiological assays necessitate growing and isolating the pathogen from the sample, which can take several days or even weeks, in addition to preparing media. Paper-based biosensors address many of these problems.

The dilution or isolation by streaking method was first developed by Loeffler and Gaffky in Koch's laboratory, which involves the dilution of bacteria by systematically streaking them over the exterior of the agar in a Petri dish to obtain isolated colonies which will then grow into quantity of cells, or isolated colonies. If the agar surface grows microorganisms which are all genetically same, the culture is then considered as a microbiological culture.

A perfect disinfectant would also offer complete and full microbiological sterilisation, without harming humans and useful form of life, be inexpensive, and noncorrosive. However, most disinfectants are also, by nature, potentially harmful (even toxic) to humans or animals. Most modern household disinfectants contain denatonium, an exceptionally bitter substance added to discourage ingestion, as a safety measure. Those that are used indoors should never be mixed with other cleaning products as chemical reactions can occur.

In practice, the term "cell culture" now refers to the culturing of cells derived from multicellular eukaryotes, especially animal cells, in contrast with other types of culture that also grow cells, such as plant tissue culture, fungal culture, and microbiological culture (of microbes). The historical development and methods of cell culture are closely interrelated to those of tissue culture and organ culture. Viral culture is also related, with cells as hosts for the viruses.

Due to its naturally selective spectrum of activity, it is also employed as a selective agent in microbiological media for the isolation of gram-negative bacteria, yeast, and moulds. Nisin has also been used in food packaging applications and can serve as a preservative by controlled release onto the food surface from the polymer packaging. In combination with miconazole it has been studied as a possible treatment for infections of Clostridium difficile.

This, however, does not prove deliberate poisoning by Napoleon's enemies: copper arsenite has been used as a pigment in some wallpapers, and microbiological liberation of the arsenic into the immediate environment would be possible. The case is equivocal in the absence of clearly authenticated samples of the wallpaper. Samples of hair taken during Napoleon's lifetime also show levels of arsenic, so that arsenic from the soil could not have polluted the post-mortem sample.

Major Alfred Whitmore (1876-1946) was an English pathologist who, together with C.S. Krishnaswami, identified Burkholderia pseudomallei, the causative agent of melioidosis (also known as "Whitmore's disease") in opium addicts in Rangoon in 1911. He differentiated it from Burkholderia mallei, the causative agent of glanders, by clinical and microbiological features. He was initially a Captain, and later a Major, in the Indian Medical Service. Later, he also became director of the Rangoon Medical School.

Water supply in most localities served by ANDA is intermittent, varying from 16 hours per day in some areas to less than 4 hours per day or even once every four days, according to a Demographic and Health Survey (called FESAL by its Spanish acronym) carried out in 2002.Encuesta Nacional de Salud Familiar FESAL Most localities, however, seem to receive water at least once a day. The microbiological quality of water is insufficient.

Organic farming has a preference for using manure as fertilizer, compared to conventional farming in general. This practise seems to imply an increased risk of microbiological contamination, such as E. coli O157:H7, from organic food consumption, but reviews have found little evidence that actual incidence of outbreaks can be positively linked to organic food production. The 2011 Germany E. coli O104:H4 outbreak, however, was blamed on organic farming of bean sprouts.

In addition to questions about symptoms, doctors will ask patients for an accurate travel history and whether he/she was near animals or ticks. Microbiological tests are available for doctors, but are expensive and often must be done by special laboratories. The antibiotic treatment available for rickettsiae infections has very few side effects, so if a doctor has a high suspicion of the disease, he or she may simply treat without doing more laboratory tests.

Exposure history is paramount to diagnosis. Diagnosis involves microbiological cultures from respiratory secretions of patients or serologically with a fourfold or greater increase in antibody titers against C. psittaci in blood samples combined with the probable course of the disease. Typical inclusions called "Leventhal-Cole- Lillie bodies" can be seen within macrophages in BAL (bronchoalveolar lavage) fluid. Culture of C. psittaci is hazardous and should only be carried out in biosafety laboratories.

Dip slides are normally used when microbiological activity is relatively high (1,000 - 100,000 CFU per milliliter of water). The dip slide results should be used only as a guide as the accuracy of the dip slide is limited as a result of the small sample size that is analyzed and the method used to obtain results. Nevertheless, dip slides may be very useful as they are very convenient, simple to use and cost effective.

Ultraviolet (UV) light for water disinfection is well established and widely used for large applications, like municipal water systems. Some hikers use small portable UV devices which meet the U.S. EPA Guide Standard and Protocol for Testing Microbiological Water Purifiers, for example, the SteriPEN. Another approach to portable UV water purification is solar disinfection (also called sodis). Clear water is sterilized by putting it in a clear polyethylene (PET) bottle and leaving it in direct sunlight for 6 hours.

Some mycobacteria contain a type of lipase (enzyme that breaks up lipid molecules); when these species are added to a mixture of polysorbate 80 and phenol red, they cause the solution to change color, so this is used as a test to identify the phenotype of a strain or isolate. On RODAC agar plates used in microbiological control, polysorbate 80 counteracts any disinfectants often found on sampled surfaces, thereby allowing the microbes found on these surfaces to grow.

This explains why most of the Fe2+ oxidizing microorganisms are only found in acidic environments and are obligate acidophiles. The best studied Fe2+ oxidizing bacterium is Acidithiobacillus ferrooxidans, an acidophililic chemolithotroph. The microbiological oxidation of Fe2+ is an important aspect of the development of acidic pH's in mines, and constitutes a serious ecological problem. However, this process can also be usefully exploited when controlled. The sulfur containing ore pyrite (FeS2) is at the start of this process.

All three brilacidin treatment arms (two single-dose regimens and one three-day dose regimen) had clinical success rates comparable to the clinical success rate of the FDA-approved seven-day dosing regimen of daptomycin. All brilacidin treatment regimens were generally well tolerated. There were six serious adverse events (SAEs) reported in the study, none of which were considered related to brilacidin by the principal investigator. The results were also positive in the microbiological intent-to-treat population (MITT).

This process is mainly used when processing Coffea arabica. After de-pulping, the beans are collected in fermentation tanks where bacterial removal of the mucilage takes place over 12 to 36 hours. The fermentation phase is important in the development of the flavour of the coffee, which is partially due to the microbiological processes that take place. The emergence of yeasts and moulds in acidic water can lead to off-flavors like sour coffee and onion-flavour.

After that date, sanitary stations, hygienic and microbiological or epidemiological services were established in Pristina, Prizren and Mitrovica. In these units there was a great lack of specialized staff (except in Prizren), but health services were performed by health employees with medical school degrees. In ancient Prizren, during 1923/1924, it was established the highly efficient bacteriological service which provided services to the entire territory of Kosovo at that time (a part of Sandžak and Montenegro).

A combination of intense chemical, physical and microbiological weathering allows the removal of REEs in upper, more acidic completely weathered layer, downward migration through rainwater and eventually, deposition (and concentration) at lower, less acidic moderately weathered layer. (REE forms a more stable complex in soil with higher pH). In addition, intense weathering in subtropical areas (i.e. South China) continuously removes significant volume of overlying materials from the in-situ weathering system, which is a process called denudation.

In this microbiological procedure, theoretically, the antibacterial or anti-fungal activity of the volatile oils from a chosen plant may be tested against a selection of gram-positive and gram-negative bacteria or a species of fungi. The growth of the bacteria or fungi are then monitored on a timely basis to measure the bacteriostatic or anti-fungal activity of the volatile oils. In some cases, a complete inhibition of growth for the bacteria tested can be observed.

The conversion of acetoin into acetyl-CoA is catalysed by the acetoin dehydrogenase complex, following a mechanism largely analogous to the pyruvate dehydrogenase complex; however, as acetoin is not a 2-oxoacid, it does not undergo decarboxylation by the E1 enzyme; instead, a molecule of acetaldehyde is released. In some bacteria, acetoin can also be reduced to 2,3-butanediol by acetoin reductase/2,3-butanediol dehydrogenase. The Voges-Proskauer test is a commonly used microbiological test for acetoin production.

However it has recently been shown that certain bacteria are capable of dramatically changing shape. Sergei Winogradsky took a middle-ground stance in the pleomorphism controversy. He agreed with the monomorphic school of thought, but disagreed with some of the foundational microbiological beliefs that the prominent monomorphists Cohn and Koch held. Winogradsky published a literature review titled "The Doctrine of Pleomorphism in Bacteriology" in which he attempted to explicate the pleomorphic debate, identifying the fundamental errors within each side's argument.

She "rented several of their bedrooms and later opened a corset shop". Falkow attributed his early interest in microbiology to reading Microbe Hunters in 1943, when he was 11 years old, which he found at the public library after the family had moved to Newport, Rhode Island. The book is a dramatization of microbiological research written by American microbiologist Paul de Kruif. Because of poor grades until his senior year of high school, an adviser suggested military rather than college.

Industrial water treatment seeks to manage four main problem areas: scaling, corrosion, microbiological activity and disposal of residual wastewater. Boilers do not have many problems with microbes as the high temperatures prevent their growth. Scaling occurs when the chemistry and temperature conditions are such that the dissolved mineral salts in the water are caused to precipitate and form solid deposits. These can be mobile, like a fine silt, or can build up in layers on the metal surfaces of the systems.

Analysis of the urine may show signs of urinary tract infection. Specifically, the presence of nitrite and white blood cells on a urine test strip in patients with typical symptoms are sufficient for the diagnosis of pyelonephritis, and are an indication for empirical treatment. Blood tests such as a complete blood count may show neutrophilia. Microbiological culture of the urine, with or without blood cultures and antibiotic sensitivity testing are useful for establishing a formal diagnosis, and are considered mandatory.

If Staphylococcus aureus infection is demonstrated by microbiological culture to be responsible (or suspected), the treatment may be changed to fusidic acid cream, an antibiotic which is effective against this type of bacteria. Aside from fusidic acid, neomycin, mupirocin, metronidazole, and chlorhexidine are alternative options in this scenario. Finally, if the condition appears resistant to treatment, investigations for underlying causes such as anemia or nutrient deficiencies or HIV infection. Identification of the underlying cause is essential for treating chronic cases.

IGRAs cannot distinguish between latent infection and active tuberculosis (TB) disease, and should not be used as a sole method for diagnosis of active TB, which is a microbiological diagnosis. A positive IGRA result may not necessarily indicate TB infection, but can also be caused by infection with non-tuberculous mycobacteria. A negative IGRA does not rule out active TB disease; a number of studies have shown that up to a quarter of patients with active TB have negative IGRA results.

Neutropenia is a distinguishing feature of GSD Ib, absent in GSD Ia. The microbiological cause of neutropenia in GSD Ib is not well understood. Broadly, the problem arises from compromised cellular metabolism in the neutrophil, resulting in accelerated neutrophil apoptosis. The neutropenia in GSD is characterized by both a decrease in absolute neutrophil count and diminished neutrophil function. Neutrophils use a specific G6P metabolic pathway which relies on the presence of G6Pase-β or G6PT to maintain energy homeostasis within the cell.

The term refers to the stereotypical view of mushroom cultivation, where mushrooms are "kept in the dark and periodically given a load of manure". In fact, the most commonly cultivated mushroom, Agaricus bisporus is grown on a pasteurized compost substrate, not raw manure (common raw ingredients in mushroom compost are horse manure and straw). The chemical and microbiological nature of finished compost is, however, quite different from raw manure. Mushrooms are fungi rather than plants and therefore do not use photosynthesis.

An autoclave uses steam and pressure to sterilize the waste or reduce its microbiological load to a level at which it may be safely disposed of. Many healthcare facilities routinely use an autoclave to sterilize medical supplies. If the same autoclave is used to sterilize supplies and treat biomedical waste, administrative controls must be used to prevent the waste operations from contaminating the supplies. Effective administrative controls include operator training, strict procedures, and separate times and space for processing biomedical waste.

As a food microbiologist, he works on foodborne illness and the microbiological safety of food and water supply. In the late 1980s, Chang discovered that the state-of-the-art method for detecting E. coli held substantial flaws. The new test, produced by Chang, provided accurate results in a day's time, versus three or four days for the century-old coliform test. Chang and the undergraduate researcher became co- inventors on a patent for "Colitag", and on two patents since.

Sputum is mucus that is coughed up from the lower airways (the trachea and bronchi). In medicine, sputum samples are usually used for naked eye exam, microbiological investigations of respiratory infections and cytological investigations of respiratory systems. It is critical that the patient not give a specimen that includes any mucoid material from the interior of the nose. Naked eye exam of sputum can be done at home by a patient in order to note the various colors (see below).

An IAC audit can be divided into two parts. One part is about the level of comfort experienced in a building and the other is about measures of IAQ. Levels of comfort in a building are determined by factors such as temperature, humidity, air velocity, air renewal, and ventilation pressure. The second part, the IAQ, is determined by factors such as inorganic toxic gases, VOCs, particulate matter (PM10), electromagnetic fields and radiation, and microbiological contaminants (fungi and bacteria such as Legionella).

A turbidostat is a continuous microbiological culture device, similar to a chemostat or an auxostat, which has feedback between the turbidity of the culture vessel and the dilution rate. The theoretical relationship between growth in a chemostat and growth in a turbidostat is somewhat complex, in part because they are similar. A chemostat has a fixed volume and flow rate, and thus a fixed dilution rate. A turbidostat dynamically adjusts the flow rate (and therefore the dilution rate) to make the turbidity constant.

E. coli culture on a Petri dish Bacteriological water analysis is a method of analysing water to estimate the numbers of bacteria present and, if needed, to find out what sort of bacteria they are. It represents one aspect of water quality. It is a microbiological analytical procedure which uses samples of water and from these samples determines the concentration of bacteria. It is then possible to draw inferences about the suitability of the water for use from these concentrations.

The aerogels were placed and retrieved by using the robotic arm outside Kibo. The first year samples were returned to Earth in mid-2016, panels from the second year were brought back in late 2017, and the last set ended exposure in February 2018. The last aerogels were placed inside the 'landing & return capsule' in early 2018 and ejected toward Earth for retrieval. After retrieving the aerogels, scientists are investigating the captured microparticles and tracks formed, followed by microbiological, organochemical and mineralogical analyses.

Graph of when laboratory tests for dengue fever become positive. Day zero refers to the start of symptoms, 1st refers to in those with a primary infection, and 2nd refers to in those with a secondary infection. The diagnosis of dengue fever may be confirmed by microbiological laboratory testing. This can be done by virus isolation in cell cultures, nucleic acid detection by PCR, viral antigen detection (such as for NS1) or specific antibodies (serology).WHO (2009), pp. 90–95.

The organic matter in sea spray consists of dissolved organic carbon (DOC) and even microbes themselves, like bacteria and viruses. The amount of organic matter in sea spray depends on microbiological processes, though the total effect of these processes is still unknown. Chlorophyll-a is often used as a proxy for primary production and organic matter content in sea spray, but its reliability for estimating DOC concentrations is controversial. Biomass often enters sea spray through the death and lysis of algal cells, often caused by viral infections.

An aerial view of a whiting event precipitation cloud in Lake Ontario. A whiting event is a phenomenon that occurs when a suspended cloud of fine- grained calcium carbonate precipitates in water bodies, typically during summer months, as a result of photosynthetic microbiological activity or sediment disturbance. The phenomenon gets its name from the white, chalky color it imbues to the water. These events have been shown to occur in temperate waters as well as tropical ones, and they can span for hundreds of meters.

Burning hydrocarbons as fuel, producing carbon dioxide and water, is a major contributor to anthropogenic global warming. Hydrocarbons are introduced into the environment through their extensive use as fuels and chemicals as well as through leaks or accidental spills during exploration, production, refining, or transport. Anthropogenic hydrocarbon contamination of soil is a serious global issue due to contaminant persistence and the negative impact on human health. When soil is contaminated by hydrocarbons, it can have a significant impact on its microbiological, chemical, and physical properties.

In 1997, he and a colleague, the late Hannah Woody published an invited extensive review article on chronic bacterial infection in Clinical Microbiological Reviews. Among their conclusions was the claim that "difficult to culture and dormant bacteria are involved in the latency of infection and that these persistent bacteria may be pathogenic." He implicated atypical bacteria in several kidney-related diseases including pyelonephritis, glomerulonephritis, idiopathic hematuria, and interstitial cystitis. He also speculated about their role in other diseases such as rheumatic fever, tuberculosis, syphilis, and rheumatoid arthritis.

On the land, phosphorus gradually becomes less available to plants over thousands of years, since it is slowly lost in runoff. Low concentration of phosphorus in soils reduces plant growth, and slows soil microbial growth - as shown in studies of soil microbial biomass. Soil microorganisms act as both sinks and sources of available phosphorus in the biogeochemical cycle. Locally, transformations of phosphorus are chemical, biological and microbiological: the major long-term transfers in the global cycle, however, are driven by tectonic movements in geologic time.

B. bovis transmission Babesia is a protozoan parasite found to infect vertebrate animals, mostly livestock mammals and birds, but also occasionally humans. Common names of the disease that Babesia microti causes are Texas cattle fever, redwater fever, tick fever, and Nantucket fever. The disease it causes in humans, babesiosis, is also called piroplasmosis. Due to historical misclassifications, the protozoan Babesia microti has been labeled with many names, including Nuttallia; the microbiological community changed the name Babesia microti to Theileria microti based on evidence from 2006.

The required extract is obtained in a kettle fitted with a steam jacket. This method of brewing prevents caramelization of the sugars. (unsaturated mead) is also made, especially in home production, wherein the must is made by mixing honey with room temperature or warm water, without boiling, allowing to retain more of the honey aroma. In order to guarantee the microbiological safety of the boiled must, it is cooled on the same day to 20–22 °C, the optimum temperature for yeast to propagate.

A second microbiological transformation commonly takes place after the alcoholic fermentation of red wines. This is usually referred to as the malolactic fermentation (MLF), in which malic acid, naturally present in grape juice, is converted into lactic acid under the influence of bacteria (it is not strictly a fermentation). MLF is almost universally practised for red wines. It often occurs naturally, owing to the presence of lactic acid bacteria in wineries, but there are also commercially available preparations of bacteria to inoculate for MLF if necessary.

The length of antibiotic courses depend on the severity of the infection and whether bone infection is involved but can range from 1 week to 6 weeks or more. Current recommendations are that antibiotics are only used when there is evidence of infection and continued until there is evidence that the infection has cleared, instead of evidence of ulcer healing. Choice of antibiotic depends on common local bacterial strains known to infect ulcers. Microbiological swabs are believed to be of limited value in identifying causative strain.

Biological methanation (also: microbiological methanation) is a conversion process to generate methane by means of highly specialized microorganisms (Archaea) within a technical system. This process can be applied in a power- to-gas system to produce biomethane and is appreciated as an important storage technology for variable renewable energy in the context of energy transition.Sterner, M. und Stadler, I.: Energiespeicher - Bedarf, Technologien, Integration. Springer Verlag, Berlin, 2014 This technology was successfully implemented at a first power-to-gas plant of that kind in the year 2015.

Esmond Emerson Snell (September 22, 1914 – December 9, 2003) was an American biochemist who spent his career researching vitamins and nutritional requirements of bacteria and yeast. He is well known for his study of lactic acid-producing bacteria, developing microbiological assays for a number of key nutrients; the discovery of more than half of known vitamins has been attributed to the use of this work. He discovered several B vitamins, including folic acid, and characterized the biochemistry of vitamin B6 (also known as pyrixodal).

Regardless, freeze-drying has been used for decades in microbiological research as a way to store and stabilize cultures. Six substances, being NaCl, sorbitol, mannitol, mannose, sodium glutamate, and betaine were tested to determine if they had any effect on the survivability of the cells after freeze-drying. Three of the six substances added had a positive effect on the growth and freeze-drying of Lactobacillus, being NaCl, sorbitol, and sodium glutamate. The results suggest that these substances have protective effects on Lactobacillus delbrueckii subsp.

Then further tests can be performed to confirm the presence of the bacteria, such as serology tests that find antibodies formed in organisms as a response to infection. In contrast, chromogenic microbiological media use particular color-producing enzymes that are targeted for metabolism by a certain strain of bacteria. Thus, if the given cultures are present, the media will become colored accordingly as the bacteria metabolize the color-producing enzyme. This greatly facilitates the identification of certain bacteria cultures and can eliminate need for further testing.

Quantitative microbiological risk assessment (QMRA) is the process of estimating the risk from exposure to microorganisms. The process involves measuring known microbial pathogens or indicators and running a Monte Carlo simulation to estimate the risk of transfer. If a dose-response model is available for the microbe, it be used to estimate the probability of infection. QMRA has expanded to be used to estimate microbial risk in many fields, but is particularly important in assessments of food water supply and human faeces/wastewater safety.

Microorganisms often have influence on insect species, in which some insects require presence of resident symbiotic bacteria for normal physiological function. In other cases, infecting bacteria may confer insect resistance against natural enemies, thus helping insect survival rates. In contrast to the positive roles some symbiotic bacteria play with regards to insects, there are a variety of microbiological interactions which hinder the host. In this case, the infecting microbe is transmitted vertically from parent to offspring, but leads to a reduction in host fitness.

Dysentery is managed by maintaining fluids using oral rehydration therapy. If this treatment cannot be adequately maintained due to vomiting or the profuseness of diarrhea, hospital admission may be required for intravenous fluid replacement. In ideal situations, no antimicrobial therapy should be administered until microbiological microscopy and culture studies have established the specific infection involved. When laboratory services are not available, it may be necessary to administer a combination of drugs, including an amoebicidal drug to kill the parasite, and an antibiotic to treat any associated bacterial infection.

Methods of application of special yeast culture to combat mold oil, widely spread in practice to improve the safety of all types of oil. In 1923–24, S. Korolev, together with the professor G.S. Inihovym and students studied the microbiological and biochemical processes of maturation of a number of hard and soft cheese, produced in the USSR. The work enabled the first time to make a harmonious synthesis of a unified theory of ripening cheeses. Prior to that, this theory put forward a Swiss scientist Freydenreyh, based on studies of only Swiss cheese.

In 1883 and for the following 40 years, Émile Roux became closely involved with the creation of what was to become the Pasteur Institute. He divided his time between biomedical research and administrative duties. In 1888, an important year in his career, he accepted the position of Director of Services, joined the editorial board of the Annales de l’Institut Pasteur, and established the first regular course on microbiological technique, which would become extremely influential in the training of many important French and foreign researchers and physicians in infectious diseases.

His laboratory strain reduced sulphates at hitherto unheard-of rates, and their speed revived a wartime possibility of using them to manufacture sulphur for industry by fermenting waste with sulphate. This would mimic the way in which most of the world's native sulphur was deposited over geological time. A post-war World sulphur shortage was damaging post-war British industry, so he and Butlin were sent to Cyrenaica to sample a sulphur spring and check specimens for even better performance.Butlin & Postgate (1954) "The microbiological formation of sulphur in Cyrenaican lakes".

He was instrumental in the planning and implementation of several UNESCO regional and international programmes in applied microbiology and biotechnology as well in the development of global networks dealing with the management and use of microbial resources and training opportunities in the fields of marine and plant biotechnology. He was a co-founder of the Microbiological Resource Centres (MIRCEN) all around the world and played a major role in the establishment of the Biotechnology Action Countil (BAC). Through these two programmes he made a considerable contribution to the development of biotechnology research and training worldwide.

These novels included a scientist as a key character, modelled after Klein and juxtaposed with a range of negative traits and ethnic stereotypes. Klein's training in Europe however allowed him to access the microbiological techniques developed by Louis Pasteur and Robert Koch, and he wrote the first major English work in bacteriology in 1884. In 1884, Klein, Alfred Lingard, and Heneage Gibbes were sent as part of the British cholera commission to Calcutta in India to verify the findings of Koch which had caused some embarrassment to the British Indian medical community.

In descemetoceles, the Descemet's membrane will bulge forward and after staining will appear as a dark circle with a green boundary, because it does not absorb the stain. Doing a corneal scraping and examining under the microscope with stains like Gram's and KOH preparation may reveal the bacteria and fungi respectively. Microbiological culture tests may be necessary to isolate the causative organisms for some cases. Other tests that may be necessary include a Schirmer's test for keratoconjunctivitis sicca and an analysis of facial nerve function for facial nerve paralysis.

From 1975 to 1983 he was Professor of Chemical Microbiology at Newcastle where he established the Microbiological Chemistry Research Laboratory (MCRL). The focus of his work was the biosynthesis, structure and biological function of various biochemical compounds, especially the discovery of teichoic acids, major components of cell wall structure of gram-positive bacteria. In 1981, Baddiley became a founding member of the World Cultural Council. After Newcastle he was awarded a senior research fellowship by the Science and Engineering Research Council, and moved to the biochemistry department at Cambridge.

Dehydrated milk and dehydrated eggs were products developed at this time for which Anellis tested the microbiological safety. Anellis's research focused on strains of bacteria which were especially heat-resistant, including salmonella and clostridium botulinum. This led to the consideration of the use of gamma radiation as a food preservative, and Anellis began research on the radiation resistance of bacteria in canned foods. In 1963 the Food and Container Institute was closed and its operations were moved to the U.S. Army Natick Research and Development Laboratories in Natick, Massachusetts.

As such unique location, the Cariaco Basin has been the site of a variety of studies since the mid-1950s. Since 1995, an international (Venezuela and United States) program has expanded the research in the basin. The CARIACO (Carbon Retention in a Colored Ocean; ) program consists of a time series station in the eastern deep of the basin which is visited on a monthly basis to collect hydrographic, nutrient and primary productivity measurements. A suite of other measurements, including a sediment trap mooring, microbiological studies and current measurements are also conducted at this site.

In 1936 Frank Horsfall, Alice Chenoweth, and colleagues developed, in mouse lung tissue, a live influenza virus vaccine. In 1939 Smith became a professor of bacteriology at the University of Sheffield and in 1946 a professor at the University College Hospital Medical School at the University of London. He retired from the U.C.H. Medical School in 1960 but continued to do research at the Microbiological Research Establishment in Porton Down. Smith was also instrumental in the introduction of polio vaccination in the UK and headed the Medical Research Council's Biological Research Board.

In theory, anthrax spores can be cultivated with minimal special equipment and a first-year collegiate microbiological education. To make large amounts of an aerosol form of anthrax suitable for biological warfare requires extensive practical knowledge, training, and highly advanced equipment. Concentrated anthrax spores were used for bioterrorism in the 2001 anthrax attacks in the United States, delivered by mailing postal letters containing the spores. The letters were sent to several news media offices and two Democratic senators: Tom Daschle of South Dakota and Patrick Leahy of Vermont.

Pulsed-power water treatment is the process of using pulsed, electro-magnetic fields into cooling water to control scaling, biological growth, and corrosion. The process does not require the use of chemicals and helps eliminate environmental and health issues associated with the use and life- cycle management of chemicals used to treat water. Pulsed-power systems have the ability to maintain low levels of microbiological activity without using corrosive chemicals. Several reports have shown that pulse-powered systems yield significantly lower counts of bacteria colony forming units compared to chemically controlled systems.

Food may be accidentally or deliberately contaminated by microbiological, chemical or physical hazards. In contrast to microbiologically caused foodborne illness, the link between exposure and effect of chemical hazards in foods is usually complicated by cumulative low doses and the delay between exposure and the onset of symptoms. Chemical hazards include environmental contaminants, food ingredients (such as iodine), heavy metals, mycotoxins, natural toxins, improper storage, processing contaminants, and veterinary medicines. Incidents have occurred because of poor harvesting or storage of grain, use of banned veterinary products, industrial discharges, human error and deliberate adulteration and fraud.

The story revolves around the theft of two germ warfare agents, botulinum toxin and the indestructible "Satan Bug" (a laboratory-conceived derivative of poliovirus), from the Mordon Microbiological Research Establishment (similar to Porton Down). There is no vaccine for the "Satan Bug" and it is so infectious that any release will rapidly destroy all human life on Earth. With these phials of unstoppable power, a mad "environmentalist" threatens the country's population unless Mordon is razed to the ground. Like other of MacLean's works, the plot involves layers of deception.

Sometimes the bacterial species are highly specialized for organochlorine respiration and even a particular electron donor, as in the case of Dehalococcoides and Dehalobacter. In other examples, such as Anaeromyxobacter, bacteria have been isolated that are capable of using a variety of electron donors and acceptors, with a subset of possible electron acceptors being organochlorines. These reactions depend on a molecule which tends to be very aggressively sought after by some microbes, vitamin B12. Bioremediation using reductive dechlorination In many instances, microbiological reductive dechlorination of chlorinated organic molecules is important for bioremediation of polluted groundwater.

The principles of lean manufacturing have been difficult at times to migrate to laboratories because they are quite different from manufacturing environments. In the hospital laboratory, for example, difficulties arise with the "staunch adherence to traditional laboratory practices, complexity of workflow, and marked variability in sample numbers." In pharmaceutical and biopharmaceutical labs, "the limiting belief" that procedures are so different that lean won't work often slow down adoption. Compared to manufacturing environments, most analytical and microbiological laboratories have a relatively low volume of samples but a high degree of variability and complexity.

Virtual colony count (VCC) is a kinetic, 96-well microbiological assay originally developed to measure the activity of defensins. It has since been applied to other antimicrobial peptides including LL-37. It utilizes a method of enumerating bacteria called quantitative growth kinetics, which compares the time taken for a bacterial batch culture to reach a threshold optical density with that of a series of calibration curves. The name VCC has also been used to describe the application of quantitative growth kinetics to enumerate bacteria in cell culture infection models.

Most widely available vegetarian cheeses are made using rennet produced by fermentation of the fungus Mucor miehei. Vegans and other dairy-avoiding vegetarians do not eat conventional cheese, but some vegetable-based cheese substitutes (soy or almond) are used as substitutes. Even in cultures with long cheese traditions, consumers may perceive some cheeses that are especially pungent-smelling, or mold-bearing varieties such as Limburger or Roquefort, as unpalatable. Such cheeses are an acquired taste because they are processed using molds or microbiological cultures, allowing odor and flavor molecules to resemble those in rotten foods.

Skills a diener needs includes physical strength, reasoning, problem solving, attention to detail, and stress tolerance. In addition to the above skills, integrity/honesty, visual identification, flexibility, and reading are other important skills a diener should possess. Another skill is the ability to work with human remains, diagnostic tools, and surgical instruments involved in a death investigation. A diener is required to be knowledgeable of lab and safety techniques including the collection and preservation of evidence and any tasks involving any chemical, biological, microbiological, pathogenic and miscellaneous hazards.

Evidence of an active microbiological ecosystem in Pitch Lake have been reported. The microbial diversity was found to be unique when compared to microbial communities analyzed at other hydrocarbon- rich environments, including the La Brea tar pits in California, and an oil well and a mud volcano in Trinidad and Tobago, among other sites. Archaeal and bacterial communities co-exist, with novel species having being discovered from Pitch Lake samples. Besides this, novel fungal life forms are described which can grow on the available asphaltenes as a sole carbon and energy source.

Microbiological culture of the sample is more sensitive (it identifies the organism in 70–85% of cases) but results can take up to 48 hours to become available. The type of white blood cell predominantly present (see table) indicates whether meningitis is bacterial (usually neutrophil- predominant) or viral (usually lymphocyte-predominant), although at the beginning of the disease this is not always a reliable indicator. Less commonly, eosinophils predominate, suggesting parasitic or fungal etiology, among others. The concentration of glucose in CSF is normally above 40% of that in blood.

In the 1950s, the station, now renamed the Chemical Defence Experimental Establishment (CDEE), became involved with the development of CS, a riot- control agent, and took an increasing role in trauma and wound ballistics work. Both these facets of Porton Down's work had become more important because of the unrest and increasing violence in Northern Ireland. On 1 August 1962, Geoffrey Bacon, a scientist at the Microbiological Research Establishment, died from an accidental infection of the plague bacterium Yersinia pestis. In the same month an autoclave exploded, shattering two windows.

The reason for such a relatively low number of deceased people from COVID-19 infection may be resulting from the vaccine programs, including the BCG vaccine, launched in the Soviet Union and Russia. Alexander Myasnikov, calling the phenomenon a "Russian Miracle", also quotes a healthy microbiota among Russians as a reason. Other medics and biologists, such as Alexander Ginzburg, director of the Epidemiological and Microbiological Research Institute in Honour of Gamaleya, also cite a high immunity among Russian people. Anna Popova, head of the Rospotrebnadzor, mentioned the effective epidemiology in Russia.

In 1905 and 1910, the Russian biologist Konstantin Mereschkowski (1855–1921) argued that plastids were reduced cyanobacteria in a symbiosis with a non-photosynthetic (heterotrophic) host that was itself formed by symbiosis between an amoeba-like host and a bacterium-like cell that formed the nucleus. Plants had thus inherited photosynthesis from cyanobacteria. In 1967, Lynn Margulis provided microbiological evidence for endosymbiosis as the origin of chloroplasts and mitochondria in eukaryotic cells in her paper, On the origin of mitosing cells. In the 1970s, Carl Woese explored microbial phylogenetics, studying variations in 16S ribosomal RNA.

Biomedical waste is a type of biowaste. Biomedical waste may be solid or liquid. Examples of infectious waste include discarded blood, sharps, unwanted microbiological cultures and stocks, identifiable body parts (including those as a result of amputation), other human or animal tissue, used bandages and dressings, discarded gloves, other medical supplies that may have been in contact with blood and body fluids, and laboratory waste that exhibits the characteristics described above. Waste sharps include potentially contaminated used (and unused discarded) needles, scalpels, lancets and other devices capable of penetrating skin.

One main advantage over other microbiological identification methods is its ability to rapidly and reliably identify, at low cost, a wide variety of microorganisms directly from the selective medium used to isolate them. The absence of the need to purify the suspect or "presumptive" colony allows for a much faster turn- around times. Another advantage is the potential to predict antibiotic susceptibility of bacteria. A single mass spectral peak can predict methicillin resistance of Staphylococcus aureus MALDI can also detect carbapenemase of carbapenem-resistant enterobacteriaceae, including Acinetobacter baumannii and Klebsiella pneumoniae.

Ascites in a person with abdominal cancer as seen on ultrasound Liver cirrhosis with ascites Routine complete blood count (CBC), basic metabolic profile, liver enzymes, and coagulation should be performed. Most experts recommend a diagnostic paracentesis be performed if the ascites is new or if the person with ascites is being admitted to the hospital. The fluid is then reviewed for its gross appearance, protein level, albumin, and cell counts (red and white). Additional tests will be performed if indicated such as microbiological culture, Gram stain and cytopathology.

More specifically, claims related to pesticide residue of increased risk of infertility or lower sperm counts have not been supported by the evidence in the medical literature. Likewise the American Cancer Society (ACS) has stated their official position that "whether organic foods carry a lower risk of cancer because they are less likely to be contaminated by compounds that might cause cancer is largely unknown." Reviews have noted that the risks from microbiological sources or natural toxins are likely to be much more significant than short term or chronic risks from pesticide residues.

Dysentery is initially managed by maintaining fluid intake using oral rehydration therapy. If this treatment cannot be adequately maintained due to vomiting or the profuseness of diarrhea, hospital admission may be required for intravenous fluid replacement. Ideally, no antimicrobial therapy should be administered until microbiological microscopy and culture studies have established the specific infection involved. When laboratory services are not available, it may be necessary to administer a combination of drugs, including an amoebicidal drug to kill the parasite and an antibiotic to treat any associated bacterial infection.

In 1920, Conn published Manual of Methods for Pure Culture Study of Bacteria, an influential work that was important in devising methods to classify bacteria. In 1923, he published a successful general textbook, Bacteriology; the text had been initiated by his father, who had died in 1917. He edited the Manual of Microbiological Methods (1957) and was a trustee of Bergey's Manual of Determinative Bacteriology (1948–65). He also published several texts on staining including Biological Stains (1925), History of Staining (1933; 1948) and Staining Procedures (1944–55; 1960).

The only method for preparing this drug prior to 1952 was a lengthy synthesis starting from cholic acid isolated from bile. In 1952 two Upjohn biochemists, Dury Peterson and Herb Murray announced that they were able to introduce this crucial oxygen atom by fermentation of the steroid progesterone with a common mold of the genus Rhizopus. Over the next several years a group of chemists headed by John Hogg developed a process for preparing cortisone from the soybean sterol stigmasterol. The microbiological oxygenation is a key step in this process.

Mycobacterial cell wall: 1-outer lipids, 2-mycolic acid, 3-polysaccharides (arabinogalactan), 4-peptidoglycan, 5-plasma membrane, 6-lipoarabinomannan (LAM), 7-phosphatidylinositol mannoside, 8-cell wall skeleton Mycobacteria are aerobic. They are bacillary in form, at least in most phases that have attracted human microbiological attention to date; they are straight or slightly curved rods between 0.2 and 0.6 µm wide and between 1.0 and 10 µm long. They are generally nonmotile bacteria, except for the species Mycobacterium marinum, which has been shown to be motile within macrophages. They are characteristically acid-fast.

The two major types of growth media are those used for cell culture, which use specific cell types derived from plants or animals, and microbiological culture, which are used for growing microorganisms, such as bacteria or fungi. The most common growth media for microorganisms are nutrient broths and agar plates; specialized media are sometimes required for microorganism and cell culture growth. Some organisms, termed fastidious organisms, require specialized environments due to complex nutritional requirements. Viruses, for example, are obligate intracellular parasites and require a growth medium containing living cells.

There were further no nivalenol metabolites found in feces or urine within the first three days. After a week of exposure to 2.5 or 5 mg nivalenol kg bw twice a day a microbiological adaptation was seen as nivalenol metabolites (de-epoxidated nivalenol) could be found in feces and urine. In rats and mice nivalenol showed to be toxic with adverse effects of growth retardation and leukopenia already noticed at lowest doses of 0.7 mg/kg bw per day. Lethal doses were dependent on the route of administration/intake of nivalenol.

Animal bites carry an increased risk of infection due to their exposure to rabies and different bacteria that animals have in their oral cavity. Microbiological studies are carried out to determine some of these infections, frequently these infections are polymicrobial with different mixtures of aerobic and anaerobic microorganisms. Some of these bacteria (not related to rabies) identified by the remains that are maintained in the bites and by exposure to other variables and change of physical environment are: Pasturella spp., Streptococcus, Staphylococcus, Moraxella, Corynebacterium, Neisseria, Fusobacterium, Bacteroides, Posphuomonoa, Capnocytophagacanimorsus, and Prevotella.

For example, this technique was used with corn to produce the largest and sweetest crops. In the early twentieth century scientists gained a greater understanding of microbiology and explored ways of manufacturing specific products. In 1917, Chaim Weizmann first used a pure microbiological culture in an industrial process, that of manufacturing corn starch using Clostridium acetobutylicum, to produce acetone, which the United Kingdom desperately needed to manufacture explosives during World War I. Biotechnology has also led to the development of antibiotics. In 1928, Alexander Fleming discovered the mold Penicillium.

Rock wool Rock wool (mineral wool) is the most widely used medium in hydroponics. Rock wool is an inert substrate suitable for both run-to-waste and recirculating systems. Rock wool is made from molten rock, basalt or 'slag' that is spun into bundles of single filament fibres, and bonded into a medium capable of capillary action, and is, in effect, protected from most common microbiological degradation. Rock wool is typically used only for the seedling stage, or with newly cut clones, but can remain with the plant base for its lifetime.

Wallemia ichthyophaga is a basidiomycetous fungus, which requires at least 1.5 M sodium chloride for in vitro growth, and it thrives even in media saturated with salt. Obligate requirement for salt is an exception in fungi. Even species that can tolerate salt concentrations close to saturation (for example Hortaea werneckii) in almost all cases grow well in standard microbiological media without the addition of salt. The fermentation of salty foods (such as soy sauce, Chinese fermented beans, salted cod, salted anchovies, sauerkraut, etc.) often involves halophiles as either essential ingredients or accidental contaminants.

Fellworth House, Nelson, home to the Cawthron Institute 1920–1970 To address long standing concerns about a lack of scientific expertise on the Cawthron Instuture Trust Board, the Cawthron Institute Trust Act 1924 was amended to enable 3 additional trustees with scientific backgrounds to be added to the board by the Minister of Science. In 1967 Barnicoat retired as Director. and was replaced in 1968 by E. B. (Barrie) Cousins, Associate Professor of Biochemistry at the University of Otago. The Chemical Services Group was established under the leadership of Alan Cooke, for the first time offering commercial chemical and microbiological analyses.

Because medical laboratory scientists are skilled in diverse scientific disciplines, employment outside of the medical laboratory is common. Many MLS are employed in government positions such as the FDA, USDA, non-medical industrial laboratories, and manufacturing. The practical experience required to obtain the bachelor's degree in medical technology give the MLS a unique understanding of the inter- relationship between microbiological and chemical testing and the resulting clinical manifestations in clinical, scientific, and industrial settings. In the United Kingdom and the United States, senior laboratory scientists, who are typically post-doctoral scientists, take on significantly greater clinical responsibilities in the laboratory.

Viral Plaques of Herpes Simplex Virus Plaque-based assays are the standard method used to determine virus concentration in terms of infectious dose. Viral plaque assays determine the number of plaque forming units (pfu) in a virus sample, which is one measure of virus quantity. This assay is based on a microbiological method conducted in petri dishes or multi-well plates. Specifically, a confluent monolayer of host cells is infected with the virus at varying dilutions and covered with a semi-solid medium, such as agar or carboxymethyl cellulose, to prevent the virus infection from spreading indiscriminately.

To date, most published testing has been run in an unvalidated, unreportable manner. The ‘standard microbiological testing’ that samples are subjected to prior to metagenomics is variable and has not included reverse transcription-polymerase chain reaction (RT-PCR) testing for common respiratory viruses or, routinely 16S/ITS PCR testing. Given the relative costs of validating and performing metagenomic versus 16S/ITS PCR testing, the second one is considered an easier and more efficient option. A potential exception to the 16S/ITS testing is blood, given the huge amount of 16S sequence available, making clean cutoffs for diagnostic purposes problematic.

Although the specific mechanisms regulating that effect are not fully understood, they are thought to be related to differential effects on soil chemical, physical, and microbiological properties by different crops. By affecting the soil in different ways, crops in a rotation help to stabilise changes in the properties. Another consideration is that many agricultural pests are species- specific ans so having a given species present in a field only some of the time helps to prevent populations of pests from growing. The organisation of individual plants in a field is also variable and typically depends on the crop being grown.

Directed therapy refers to the treatment of infections based on specific knowledge of what the causal agent is able to be treated with. It is the opposite to empiric therapy, which refers to the treatment of infections based on the clinical suspicion about what the agent should be able to be treated with, based on experience or guidelines. Information that directs therapy may medical tests that isolate the cause of an infection, such as microbiological culture, or polymerase chain reaction testing, as well as testing for antimicrobial sensitivities. Often, directed therapy occurs after initial empiric therapy.

In microbiological laboratories, B. anserina bacteria can be grown on special protein-enriched media (rich in ovoalbumins or animal tissue (that contains myoglobin)), in anaerobic conditions. They can also be grown in embryonic chicken eggs. The laboratory cultivation of B. anserina is rarely done and constitutes a diagnostic method in bird borreliosis and spirochetosis. B. anserina used to be maintained in embryonic chicken eggs or by serial passages in domestic chickens until in 1986 it was discovered that it could be cultivated in Barbour-Stoenner-Kelly (BSK) medium, which facilitated and made future research more cost-effective.

Fluparoxan was not metabolised by human cytochrome P450 enzymes CYP 1A and CYP 2A, and was found not to be a mutagen in cultured human peripheral lymphocytes and did not cause gene mutation when administered to Chinese hamster fibroblasts in culture. No mutagenic potential was identified in microbiological mutagenicity tests including a fluctuation test with S9 activation. No hydroxylated metabolites were identified after incubation with rat liver microsomes (S9) or in rat urine following oral dosing. The compound was well tolerated on repeat oral administration to rat (≤ 200 mg /kg/day) and dog (≤ 80 mg/kg/day) for 12 months.

Oxygen is naturally present in most food and food packages as it is a major component in air. However, oxygen is also one of the great causes or needs for aging of biological substances, due to its source for increase of chemical and microbiological activity. Today, methods like [Modified atmosphere] (MAP) and [Controlled atmosphere] packaging (CAP) are implemented to reduce and control the oxygen content in food packages to prolong [shelf life] and ensure safe food. To assure the effectiveness of these methods it is important to regularly measure the concentration of oxygen (and other gases) inside these packages.

"Treble Cross" was filmed over two weeks in September 1967, during which time Century 21's next Supermarionation series, Joe 90, entered pre-production. The scale model representing Slaton Hospital previously appeared as the microbiological laboratory in "Place of Angels". For realism, during the filming of the revival scenes the front of the Major Gravener puppet was fitted with an air bag to make it appear that the character's chest is rising and falling. Footage showing the Spectrum forces converging on Weston Airstrip is duplicated from "Manhunt", another episode in which Spectrum attempts to apprehend Captain Black.

October 2006. p. 11. The textbook Food Science defines food science in simpler terms as "the application of basic sciences and engineering to study the physical, chemical, and biochemical nature of foods and the principles of food processing". Activities of food technologists include the development of new food products, design of processes to produce these foods, choice of packaging materials, shelf-life studies, sensory evaluation of products using survey panels or potential consumers, as well as microbiological and chemical testing. Food scientists may study more fundamental phenomena that are directly linked to the production of food products and its properties.

Traditionally, the movement of groundwater has been studied separately from surface water, climatology, and even the chemical and microbiological aspects of hydrogeology (the processes are uncoupled). As the field of hydrogeology matures, the strong interactions between groundwater, surface water, water chemistry, soil moisture and even climate are becoming more clear. California and Washington both require special certification of hydrogeologists to offer professional services to the public. Twenty-nine states require professional licensing for geologists to offer their services to the public, which often includes work within the domains of developing, managing, and/or remediating groundwater resources.

Nanobacterium sanguineum was proposed in 1998 as an explanation of certain kinds of pathologic calcification (apatite in kidney stones) by Finnish researcher Olavi Kajander and Turkish researcher Neva Ciftcioglu, working at the University of Kuopio in Finland. According to the researchers the particles self-replicated in microbiological culture, and the researchers further reported having identified DNA in these structures by staining. A paper published in 2000 by a team led by an NIH scientist John Cisar further tested these ideas. It stated that what had previously been described as "self-replication" was a form of crystalline growth.

Bronchial brushing is a procedure in which cells are taken from the inside of the airway mucosa or bronchial lesions through catheter-based brushing under direct visualization or fluoroscopic guidance. Flexible brushes are passed through the bronchoscope, and the bronchial surface is gently abraded to obtain the specimen. Various types of bronchial brush may be used to collect both cellular and microbiological material, using direct vision when collecting from proximal areas of suspicion or fluoroscopic screening when sampling more peripheral sites. A bronchial brushing is used to find cancer and changes in cells that may lead to cancer.

Anellis continued his research on the radiation resistance of bacteria at the Natick Labs until his retirement in 1977. While working at the Natick Labs he also participated in the program to develop foods and food preservations for NASA. Anellis was an advocate of irradiation of foods as a food preservative and preventative against microbiological contamination, and testified before the U.S. Congress and the U.S. Food and Drug Administration on the safety of human consumption of foods irradiated at low dosage.LUDLOW, Marian. “Microbial Work is No Small Task: Scientist’s achievements recognized in research”, The Lake Sentinel, Wednesday, December 27, 1989, 3–4.

Health problems associated with high levels of airborne mold spores include allergic reactions, asthma episodes, irritations of the eye, nose and throat, sinus congestion, and other respiratory problems, although mold spores won't actually cause asthma, just irritate existing conditions. For example, residents of homes with mold are at an elevated risk for both respiratory infections and bronchitis. When mold spores are inhaled by an immunocompromised individual, some mold spores may begin to grow on living tissue, attaching to cells along the respiratory tract and causing further problems.Simicic S, Matos T, “Microbiological diagnosis of invasive aspergillosis.” Zdravnisji vestnik-slovanian medical journal.

A later posting from a Guardian editor stated that Neal's Yard was "working on replies". Following the posting of questions about the efficacy of their remedies, and comments of a sceptical nature towards Neal's Yard alternative medicines, the company declined to participate in the discussion, and the thread was closed. The refusal of Neal's Yard Remedies to answer any of the questions was criticised by public relations experts. In October 2013, the United States Food and Drug Administration issued an import alert regarding the barring of shipments of the company's Cocoa Eye Shadow from entry into the U.S. due to microbiological contamination.

All of the aforementioned anthrax decontamination technologies have been demonstrated to be effective in laboratory tests conducted by the US EPA or others. Decontamination techniques for Bacillus anthracis spores are affected by the material with which the spores are associated, environmental factors such as temperature and humidity, and microbiological factors such as the spore species, anthracis strain, and test methods used. A bleach solution for treating hard surfaces has been approved by the EPA. Chlorine dioxide has emerged as the preferred biocide against anthrax-contaminated sites, having been employed in the treatment of numerous government buildings over the past decade.

Rittmann is one of the pioneers in developing and applying mathematical models of biofilms, which are microorganisms that grow attached to a solid surface. Although some biofilms are infamous for causing infections or fouling the surfaces of pipes, ships, and membranes, Rittmann focuses on the good biofilms used to treat contaminated water. Mathematical modeling is a powerful tool to integrate the several microbiological, chemical, and transport processes that occur together in a biofilm. Models can represent the gradients in substrates that the microorganisms metabolize, the products generated by the microorganisms, and the different types of microorganisms that exist together in biofilms.

Rittmann and several colleagues were the first to define soluble microbial products (SMP), which comprise a wide range of soluble organic molecules that microorganisms release to their environment. With Dr. Chrysi Laspidou, Rittmann linked SMP to the solid-phase products generated by microorganisms, the extracellular polymeric substances (EPS); they created the “unified model” of SMP, EPS, and active biomass, and it has been expanded and applied to all types of microbiological processes. Being major sinks for electrons and carbon, SMP and EPS have profound impacts on the performance of environmental biotechnologies in terms of effluent quality and the composition of the biomass.

Aflatoxins are produced by both Aspergillus flavus and Aspergillus parasiticus, which are common forms of 'weedy' molds widespread in nature. The presence of those molds does not always indicate that harmful levels of aflatoxin are present, but does indicate a significant risk. The molds can colonize and contaminate food before harvest or during storage, especially following prolonged exposure to a high-humidity environment, or to stressful conditions such as drought. The native habitat of Aspergillus is in soil, decaying vegetation, hay, and grains undergoing microbiological deterioration, but it invades all types of organic substrates whenever conditions are favorable for its growth.

Internationally, JECFA has set the Acceptable Daily Intake (ADI) of Class I caramel color as "not specified"; that of Class II as 0–160 mg/kg body weight; and that of Class III & IV as 0–200 mg/kg body weight. The United States Food and Drug Administration (FDA) classifies and regulates caramel color in Title 21 CFR § 73.85 as an approved color additive exempt from certification. Unless a food has a standard of identity, caramel color may be safely used in foods generally at levels consistent with "good manufacturing practice" (GMP). Caramel color has excellent microbiological stability.

Although Domingue's primary research focus was on bacterial L-forms, he also published extensively on the biological significance of the enterobacterial common antigen of gram negative bacteria– its antigenicity, immunogenicity, and vaccine potential against urinary tract infections. He studied the immunological consequences of a vasectomy, as well as the role of various gram negative pathogens in the host-pathogen interaction in pyelonephritis, and the effects of antibiotics and chemotherapy on urinary tract infections. He also published microbiological and immunological studies on bacteria that produce chorionic gonadotropin-like hormone and their role in an experimental tumor model.

ISOPP, the International Society of Oncology Pharmacy Practitioners, splits the definition of a closed system into two different categories: # "closed" in terms of microbiological contamination. This definition deals purely with introducing micro-organisms into a sterile product, and there is no consideration of the sterile product coming out of the vial contaminating the environment.ISOPP Journal of Oncology Pharmacy Practice Volume 13, 2007, pg 28-29. # "closed" in relation to chemical contamination and refers to drug transfer devices that mechanically prohibit the transfer of environment contaminants into the system and the escape of hazardous drug or vapor concentrations outside the system.

He then started graduate research in Botany whilst also teaching in the department of botany. This period was key to his lifelong devotion to scientific study of plant physiology and agriculture. It enabled him to take a microbiological view of plant structure whilst addressing the soil as a variable environment (either favourable or unsuitable). He presented his doctoral research in 1919, and it was published in the journal Soil Science in 1920 titled 'Symbiotic nitrogen fixation as influenced by nitrogen in the soil' His paper concluded that the nitrogen level in soil had no significant effect on fixation by legumes.

This is a list of Legionnaires' disease outbreaks; Legionnaire's is a potentially fatal infectious disease caused by gram negative, aerobic bacteria belonging to the genus Legionella. The first reported outbreak was in Philadelphia, Pennsylvania in 1976 during a Legionnaires Convention at the Bellevue-Stratford Hotel. An outbreak is defined as two or more cases where the onset of illness is closely linked in time (weeks rather than months) and in space, where there is suspicion of, or evidence of, a common source of infection, with or without microbiological support (i.e. common spatial location of cases from travel history).

Since healthcare facilities can house a number of different types of patients who potentially have weakened immune systems, aerobiological engineering is of significant importance to engineers of hospitals. The aerobiology that concerns designers of hospitals includes viruses, bacteria, fungi, and other microbiological products such as endotoxins, mycotoxins, and microbial volatile organic compounds (MVOC's). Bacteria and viruses, because of their small size, readily become airborne as bacterial aerosols and can remain suspended in the air for hours. Because of this, adequate precautions and mitigation techniques need to be taken with indoor air quality in hospitals dealing with infectious diseases.

Initially the institute was founded to combat infectious diseases and to make and distribute serum preparations and vaccines. The early organisations were the State Serum Laboratory (1911–1947; provisional 1911–1914), the State Serum Institute (1947–1970) and the Public Health Laboratory (1970–1981). The new Act in 1982 paved way for its transformation from a practical microbiological and clinical chemistry laboratory towards a research institute specializing in public health and prevention of diseases. This development was also seen in the organisation structure; new departments in Epidemiology and Environmental Health (originally Toxicology and Environmental Hygiene) were founded.

This secondary antibody's binding sites are specific for the primary antibody that's already bound to the antigen, and therefore the secondary antibody binds to the primary antibody. This method allows for more fluorophore-tagged antibodies to attach to their target, thus increasing the fluorescent signal during microscopy. Immunofluorescence is a technique used for light microscopy with a fluorescence microscope and is used primarily on microbiological samples. This technique uses the specificity of antibodies to their antigen to target fluorescent dyes to specific biomolecule targets within a cell, and therefore allows visualization of the distribution of the target molecule through the sample.

Microbial cultures on solid and liquid media A microbiological culture, or microbial culture, is a method of multiplying microbial organisms by letting them reproduce in predetermined culture medium under controlled laboratory conditions. Microbial cultures are foundational and basic diagnostic methods used as a research tool in molecular biology. Microbial cultures are used to determine the type of organism, its abundance in the sample being tested, or both. It is one of the primary diagnostic methods of microbiology and used as a tool to determine the cause of infectious disease by letting the agent multiply in a predetermined medium.

Sadie Hawkins Day and double whammy are two terms attributed to Al Capp that have entered the English language. Other, less ubiquitous Cappisms include skunk works and Lower Slobbovia. The term shmoo also has entered the lexicon, defining highly technical concepts in no fewer than four separate fields of science, including the variations shmooing (a microbiological term for the "budding" process in yeast reproduction), and shmoo plot (a technical term in the field of electrical engineering). In socioeconomics, a "shmoo" refers to any generic kind of good that reproduces itself, (as opposed to "widgets" which require resources and active production).

Agar has been used as an ingredient in desserts throughout Asia, and also as a solid substrate to contain culture media for microbiological work. Agar can be used as a laxative, an appetite suppressant, a vegetarian substitute for gelatin, a thickener for soups, in fruit preserves, ice cream, and other desserts, as a clarifying agent in brewing, and for sizing paper and fabrics. The gelling agent in agar is an unbranched polysaccharide obtained from the cell walls of some species of red algae, primarily from tengusa (Gelidiaceae) and ogonori (Gracilaria). For commercial purposes, it is derived primarily from ogonori.

Pseudovitamin-B12 refers to B12-like analogues that are biologically inactive in humans. Most cyanobacteria, including Spirulina, and some algae, such as Porphyra tenera (used to make a dried seaweed food called nori in Japan), have been found to contain mostly pseudovitamin-B12 instead of biologically active B12. These pseudo-vitamin compounds can be found in some types of shellfish, in edible insects, and at times as metabolic breakdown products of cyanocobalamin added to dietary supplements and fortified foods. Pseudovitamin-B12 can show up as biologically active vitamin B12 when a microbiological assay with Lactobacillus delbrueckii subsp.

The majority of these water supply systems face problems with either nitrate pollution due to extensive agriculture production and/or pollution with pesticides or bacterial contamination. All water supplies, including small private supplies, are under regular control by the local authorities and action is taken if the water quality is poor.European Environment and Health Committee: Denmark - Progress towards Regional Priority Goal 1 on water and sanitation In 2009, the proportion of microbiological tests which complied with legislative requirements was more than 96%. The quality of the drinking water is checked at the waterworks, in the distribution network and at consumers' taps.

This more specified resistance is linked to pathogenic bacteria and thus broken down into two further subsets, microbiological and clinical. Resistance linked microbiologically is the most common and occurs from genes, mutated or inherited, that allow the bacteria to resist the mechanism associated with certain antibiotics. Clinical resistance is shown through the failure of many therapeutic techniques where the bacteria that are normally susceptible to a treatment become resistant after surviving the outcome of the treatment. In both cases of acquired resistance, the bacteria can pass the genetic catalyst for resistance through conjugation, transduction, or transformation.

In 1896 Émile Marchoux, a French physician and microbiologist who had studied under Louis Pasteur, founded a microbiological laboratory in Saint-Louis, then the capital of French Colonial Senegal. In 1913 the facility was moved to Dakar which had become the new capital in 1902. After French Colonial Senegal, the institute continued its operations into the era of Senegalese independence. The IPD is primarily focused on the study of microbiology and virology, specifically arbovirus; yellow fever was first isolated in Africa at the institute, and the first vaccine for the disease was discovered at the IPD.

Phages in practice are applied orally, topically on infected wounds or spread onto surfaces, or used during surgical procedures. Injection is rarely used, avoiding any risks of trace chemical contaminants that may be present from the bacteria amplification stage, and recognizing that the immune system naturally fights against viruses introduced into the bloodstream or lymphatic system. Individualised phage therapy was successfully used by Robert T. Schooley and others to treat a case of multi-drug-resistant Acinetobacter baumannii in the U.S. in 2015. Reviews of phage therapy indicate that more clinical and microbiological research is needed to meet current standards.

Subsequent rainy seasons flooded the small cabin that served as a summer residence for concessionaires who operated a snack stand from the lower level and patio, and by 1990 the facility was demolished. Over the past four decades, budgeting has limited the Forest Service's ability to maintain the lake and its feeder pipeline. Then years of drought reduced the lake's water levels which continued microbiological contamination of the water, putting it off limits to any type of swimming at all. Following a good rainy season, the lake may be stocked with fish, typically rainbow trout from the government hatcheries.

Disgust, one of the basic emotions, may have an important role in certain forms of morality. Disgust is argued to be a specific response to certain things or behaviors that are dangerous or undesirable from an evolutionary perspective. One example is things that increase the risk of an infectious disease such as spoiled foods, dead bodies, other forms of microbiological decomposition, a physical appearance suggesting sickness or poor hygiene, and various body fluids such as feces, vomit, phlegm, and blood. Another example is disgust against evolutionary disadvantageous mating such as incest (the incest taboo) or unwanted sexual advances.

Food Testing Laboratories Apart from detecting spoilage, microbiological tests can also determine germ content, identify yeasts and molds, and salmonella. For salmonella, scientists are also developing rapid and portable technologies capable of identifying unique variants of Salmonella . Rapid Testing and Identification of Salmonella in Foods Polymerase Chain Reaction (PCR) is a quick and inexpensive method to generate numbers of copies of a DNA fragment at a specific band ("PCR (Polymerase Chain Reaction)," 2008). For that reason, scientists are using PCR to detect different kinds of viruses or bacteria, such as HIV and anthrax based on their unique DNA patterns.

He was Hull's Dean of Science from 1968 to 1970, and its pro-vice-chancellor from 1977 to 1980. Dawes was granted emeritus status in 1990, and awarded an honorary Doctorate of Science by the university in 1992. Dawes was an editor of the Biochemical Journal from 1958 to 1965 and the Journal of General Microbiology from 1971 to 1976, and served as editor-in-chief of the latter between 1976 and 1981. In 1981 he became Publications Manager of the Federation of European Microbiological Societies, and the following year commenced as Chief Editor of its FEMS Microbiology Letters journal.

A version of Snell's microbiological assay method based on the experimental organism Lactobacillus casei (now known as Lactobacillus rhamnosus) is still used as a method for detecting folates in blood. Snell's interest in isolating and characterizing unknown nutrients and growth factors also led to the serendipitous discovery of useful biochemical tools. While working to characterize the yeast growth factor that would become known as biotin, Snell and coworkers discovered the egg white protein avidin, which binds biotin with extremely high affinity. At the time avidin was noted as a cause of "egg white injury", a form of biotin deficiency in animals.

Increased levels of bleeding on probing was present at 67% of sites where there is peri-implant mucositis as it is indicative of the presence of active disease and inflammation of the peri- implant mucosa. A light probing force of 0.25N should be used to probe the gingival margins so as not to damage the soft periodontal tissues. Bleeding on probing can be used in order to predict future loss of support from surrounding tissues. Microbiological testing was shown to improve the prognostic features compared to recording bleeding on probing alone as this was better for recognising the disease advancement around implants.

Example of an Etest, which uses a plastic strip impregnated with an antibiotic at a range of concentrations Testing for antibiotic sensitivity usually occurs in a laboratory. Once a bacterium has been identified following microbiological culture, antibiotics are selected for susceptibility testing. Susceptibility testing methods are based on exposing bacteria to antibiotics and observing the response (phenotypic testing), or specific genetic tests (genetic testing). Methods used may be qualitative, meaning a result indicates resistance is or is not present; or quantitative, using a minimum inhibitory concentration (MIC) to describe the concentration of antibiotic to which a bacterium is sensitive.

Impedance microbiology is a rapid microbiological technique used to measure the microbial concentration (mainly bacteria but also yeasts) of a sample by monitoring the electrical parameters of the growth medium. It is based on the fact that bacteria metabolism transforms uncharged (or weakly charged) compounds into highly charged compounds thus changing the growth medium electrical properties. The microbial concentration is estimated on the time required for the monitored electrical parameters to deviate from the initial baseline value. Different instruments (either built in a laboratory or commercially available) to measure the bacterial concentration using Impedance Microbiology are available.

During the 2014 Ebola outbreak in West Africa, UC Rusal provided logistical support to the international relief efforts. In 2015, the company invested $10 million to build the "Centre for epidemic and microbiological research and treatment" in Guinea to fight the spread of the virus. It also donated medication, as well as sanitary equipment to the Guinean Health Ministry, and was involved in setting up a mobile hospital containing 200 beds. Field trials for a Russian Ebola vaccine were carried out at the centre, and the vaccine was officially launched in August 2017 in Kindia, where the centre is located.

A low-pressure mercury-vapor discharge tube floods the inside of a biosafety cabinet with shortwave UV light when not in use, sterilizing microbiological contaminants from irradiated surfaces. Ultraviolet germicidal irradiation (UVGI) is a disinfection method that uses short-wavelength ultraviolet (ultraviolet C or UV-C) light to kill or inactivate microorganisms by destroying nucleic acids and disrupting their DNA, leaving them unable to perform vital cellular functions. UVGI is used in a variety of applications, such as food, air, and water purification. UV-C light is weak at the Earth's surface since the ozone layer of the atmosphere blocks it.

As of 2004, the distinction between bactericidal and bacteriostatic agents appeared to be clear according to the basic/clinical definition, but this only applies under strict laboratory conditions and it is important to distinguish microbiological and clinical definitions. The distinction is more arbitrary when agents are categorized in clinical situations. The supposed superiority of bactericidal agents over bacteriostatic agents is of little relevance when treating the vast majority of infections with gram-positive bacteria, particularly in patients with uncomplicated infections and noncompromised immune systems. Bacteriostatic agents have been effectively used for treatment that are considered to require bactericidal activity.

David Taylor interview, Skanda Vale website (wmv video file). The Welsh Assembly refused to carry out a second test to confirm exposure to bacteria.Hindustan Times report According to a report by the Welsh Assembly, whether an animal is suffering from TB can only be shown by post-mortem examination or by microbiological analysis after death, but they say the test for exposure to the bacteria that cause the disease is 99.9% accurate and is recognized by the European Union and by the World Organisation for Animal Health. Against this, Skanda Vale argued that, if Shambo had bovine TB, he could be treated using antibiotics.

The acid-fastness of Mycobacteria is due to the high mycolic acid content of their cell walls, which is responsible for the staining pattern of poor absorption followed by high retention. Some bacteria may also be partially acid-fast, such as Nocardia. Acid-fast organisms are difficult to characterize using standard microbiological techniques, though they can be stained using concentrated dyes, particularly when the staining process is combined with heat. Some, such as Mycobacteria, can be stained with the Gram stain, but they do not take the crystal violet well and thus appear light purple, which can still potentially result in an incorrect gram positive identification.

In chronic pelvic pain there are no standard diagnostic tests in males; diagnosis is by exclusion of other disease entities. Chronic pelvic pain (category IIIB) is often misdiagnosed as chronic bacterial prostatitis and needlessly treated with antibiotics exposing the patient to inappropriate antibiotic use and unnecessarily to adverse effects with little if any benefit in most cases. Within a Bulgarian study, where by definition all patients had negative microbiological results, a 65% adverse drug reaction rate was found for patients treated with ciprofloxacin in comparison to a 9% rate for the placebo patients. This was combined with a higher cure rate (69% v 53%) found within the placebo group.

The proposed change argued that nomenclatural regulation of these ranks, such as serotype and morphotype, is necessary to avoid confusion. In proposed recommendation 8a(7), it was asked that "authorization be given for the use of the terms chemovar and chemotype," defining the terms as being "used to designate an infrasubspecific subdivision to include infrasubspecific forms or strains characterized by the production of some chemical not normally produced by the type strain of the species." The change to the Code was approved in August 1962 by the Judicial Commission of the International Committee of Bacteriological Nomenclature at the VIII International Microbiological Congress in Montreal.Clark WA, and Seeliger HPR. 1963.

Detailed minutes concerning actions taken in the emendation of the International Code of Nomenclature of Bacteria and Viruses during the meetings of the Judicial Commission of the International Committee of Bacteriological Nomenclature at the VIII International Microbiological Congress in Montreal August, 1962. International Bulletin of Bacteriological Nomenclature and Taxonomy, 13(1): 1-22. A good example of a plant with many polymorphic chemotypes is Thymus vulgaris. While largely indistinguishable in appearance, specimens of T. vulgaris may be assigned to one of seven different chemotypes, depending on whether the dominant component of the essential oil is thymol, carvacrol, linalool, geraniol, sabinene hydrate (thuyanol), α-terpineol, or eucalyptol.

The theory was first articulated in 1905 and 1910 by the Russian botanist Konstantin Mereschkowski, and advanced and substantiated with microbiological evidence by Lynn Margulis in 1967. Among the many lines of evidence supporting symbiogenesis are that new mitochondria and plastids are formed only through binary fission, and that cells cannot create new ones otherwise; that the transport proteins called porins are found in the outer membranes of mitochondria, chloroplasts and bacterial cell membranes; that cardiolipin is found only in the inner mitochondrial membrane and bacterial cell membranes; and that some mitochondria and plastids contain single circular DNA molecules similar to the chromosomes of bacteria.

For this reason, cystine and tyrosine quantities were studied as well, because the two share similar biological characteristics with methionine and phenylalanine, respectively. Acid hydrolyzates as well as microbiological assays were used in the quantification of amino acid content in the foods. Edwards observed differences in amino acid content between similar foods; for example, she found that bologna contained more amino acids than frankfurters and that lima beans had more cysteine and valine than pork and beans. The purpose of this study, Edwards noted, was to provide knowledge on amino acid content, such that people can consciously pair certain foods together for optimal intake.

PPV is used to indicate the probability that in case of a positive test, that the patient really has the specified disease. However, there may be more than one cause for a disease and any single potential cause may not always result in the overt disease seen in a patient. There is potential to mix up related target conditions of PPV and NPV, such as interpreting the PPV or NPV of a test as having a disease, when that PPV or NPV value actually refers only to a predisposition of having that disease. An example is the microbiological throat swab used in patients with a sore throat.

In 1902, Thom went to study with George F. Atkinson at Cornell University; two colleagues included Benjamin Duggar and Herbert Hice Whetzel, who both later became noted botanists. Two years later, he accepted a position as dairy mycologist, working with Herbert William Conn, in charge of "cheese investigations" at the Storrs Agricultural Experiment Station in Connecticut. He remained in this institution—a branch of the U.S. Department of Agriculture (USDA)— holding various research and administrative positions, until his retirement in 1942. During his employment there, Thom investigated the process of cheese ripening and sought to understand the composition of the microbiological flora required for imparting certain flavors on cheeses.
|
|
Through this work he isolated and identified the fungi Penicillium camemberti and Penicillium roqueforti. Thom identified the fungi responsible for imparting flavors to cheeses such as Roquefort. In 1914, Thom became the Chief of the Microbiological Laboratory at the USDA Bureau of Chemistry, where his job was to study problems with the handling and processing of foods, and to enforce the Pure Food and Drug Act, a United States federal law that mandated federal inspection of food products. Known for his dedication to maintaining high standards in the food industry, he relished arguing court cases "in defense of sanitary practices in the handling and processing of perishable foods".

At a microbiological laboratory near Manchester, England, Dr Denton and his assistant, Judy Chapman, activate a culture of K14, a synthetic virus. Later, as Chapman is driving home in her car, Captain Black (voiced by Donald Gray) sets a trap for her by blocking the road with a fuel tanker. Chapman crashes into the tanker and is killed instantly, whereupon she is reconstructed by the Mysterons (voiced by Donald Gray) to carry out their threat to destroy the "Place of the Angels". Returning to the laboratory, the Mysteron agent strangles a security guard with a pair of mechanical hands and steals the vial containing the K14.

The gained international appreciation of the Faculty of Veterinary Medicine as a renowned higher education establishment, motivated many countries to send their citizens for obtaining a degree in veterinary medicine in Bulgaria after the academic year 1947–1948. About 400 foreign citizens from 46 countries graduated from the FVM and another 60 had finished their PhD studies here. The FVM is the place of birth of almost all directions of Bulgarian veterinary science. The genesis and the first generation of scientists of two eminent Bulgarian scientific schools are linked to the faculty: the microbiological school of academician Stefan Angelov and the pathomorphological one of academician Ksenofont Ivanov.

On these ground of rapid expansion of microbial ecology, IAMS, International Association of Microbiological Societies, (modified its name to IUMS after 1980) decided to establish ICOME, International Commission of Microbial Ecology, at the 10th International Congress of Microbiology in Mexico City 1970. The ICOME started the next year. A role stressed for the establishment of ICOME was its active participation in the environmental problems, water and soil pollution and deterioration of environments by human activities. However, the years after Mexico showed that the interest of the Committee was not restricted to the environmental problems, but extended to the central themes of microbial ecology, i.e.

The Ravalli County Museum, founded in 1955, is located in the former Ravalli County Courthouse and focuses on County history, natural history and art. In the summer of 2000, Hamilton made international headlines when forest fires throughout the Bitterroot Valley filled the area with smoke and prompted the evacuation of many residents. President Clinton declared a state of emergency in the area and dispatched National Guardsmen to assist with fighting the fires. Hamilton is, as of 2004, home to two microbiological research and production facilities: the government-run Rocky Mountain Laboratories, and a branch of the Corixa Corporation (bought in the late 1990s from Ribi ImmunoChem Research, Inc.).

The Algatron was a proposed and prototyped waste filtration and recycling system to be implemented on NASA missions. Designed and built by a pair of sanitary engineers at the University of California, Berkeley, William J. Oswald and Clarence Golueke, the Algatron relied on algae to provide carbon Dioxide absorption and oxygen generation as well as "microbiological waste conversion" for "humans sealed within an isolated capsule.".Oswald, Golueke, and Horning, "Closed Ecological Systems," A working model was built by Oswald and Golueke in 1965 or 1966 under a contract by from the Air Force Cambridge Research Laboratories. Composed of two stacked cylinders lined with Algae, the cylinders would spin in opposite directions.

After graduation in chemistry he worked for a year at the Philip R. Park Research Foundation taking care of an animal colony and assisting with growth experiments on synthetic amino acid diets. One of these was the experiment by Geiger that first demonstrated that the essential amino acids must be present simultaneously for growth to occur. He returned to graduate school at the UCLA chemistry department with professor of biochemistry M.S. Dunn to develop microbiological methods for the quantitation of the pyrimidines. The day after graduating on 19 June 1949, he married Elizabeth Furlong and the next day left for New York City and the Rockefeller Institute for Medical Research.

The key measures necessary for preventing neonatal GBS early onset disease continue to be universal prenatal screening by culture of GBS from swabs collected from the lower vagina and rectum, correct collection and microbiological processing of the samples, and proper implementation of intrapartum antibiotic prophylaxis. The ACOG now recommends performing universal GBS screening between 36 and 37 weeks of gestation. This new recommendation provides a five-week window for valid culture results that includes births that occur up to a gestational age of at least 41 weeks. The culture-based screening approach is followed in most developed countries such as the United States, France, Spain Belgium, Canada, Argentina, and Australia.

IGNITE 4 assessed twice-daily intravenous eravacycline(1.0 mg/kg every 12 hours) compared to those receiving meropenem (1g every 8 hours). The study enrolled 500 adult patients with the primary endpoint being clinical response at the test-of-cure visit which is 25–31 days after initial dosing. Primary efficiency analysis was conducted using a 12.5% non-inferiority margin in the microbiological intent-to-treat (micro-ITT) population. On July 25, 2017 Tetraphase pharmaceuticals released top line data via press showing clinical cure rates in the micro-ITT population to be 90.8% and 91.2% for eravacycline (n=195) and meropenem (n=205), respectively (95% CI: -6.3%,5.3%).

Lysozyme in donkey milk is present in large amounts, indeed ranges from 1.0 mg/mL to 4 mg/mL, depending on the analytical method used (chemical or microbiological); this substance is present also in human (0.12 mg/ml) but only in trace amounts in cow and goat milk. Lysozyme in donkey milk is highly thermo-stable and is very resistant to acid and protease and may play a significant role in the intestinal immune response. In donkey mammary secretion, defatted or not, growth factors and hormones have also been determined. In detail, donkey mammary secretions contain human-like leptin at levels close to human milk (3.35 e 5.32 ng/mL milk).

In particular vitamin C content in donkey milk is almost 4 times more of cow's milk. Donkey milk contain more lactoferrin of cow milk and a considerable mounts of lysozyme, from 1.0 mg/mL to 4 mg/mL (depending on the analytical method used: chemical or microbiological), instead cow's milk only traces. For this reason, it has the potentiality, when properly formulated, to reduce problem skin with eczema, acne, psoriasis and herpes and properties in calming the irritation symptoms as reported by some authors. Some authors have preliminarily evaluated whether the use of a face cream made from donkey milk affected the perception of some sensory aspects.

Safe household water storage is a critical component of a Household Water Treatment and Safe Storage (HWTS) system being promoted by the World Health Organization (WHO) worldwide in areas that do not have piped drinking water. In these areas it is not uncommon for drinking water to be stored in a pot, jar, crock or other container in the home. Even if this drinking water was of acceptable microbiological quality initially, it can become contaminated from dirty hands and utensils, such as dirty dippers and cups. Drinking water containers with "narrow dispensers are key" to keeping water from being contaminated while being stored in the home.

Freshwater environmental quality parameters are those chemical, physical or biological parameters that can be used to characterise a freshwater body. Because almost all water bodies are dynamic in their composition, the relevant quality parameters are typically expressed as a range of expected concentrations. They include the natural and man-made chemical, biological and microbiological characteristics of rivers, lakes and ground-waters, the ways they are measured and the ways that they change. The values or concentrations attributed to such parameters can be used to describe the pollution status of an environment, its biotic status or to predict the likelihood or otherwise of a particular organisms being present.

Historically, virology has been considered a subdiscipline of microbiology. The motivation for founding a society specifically for virologists dates to the mid-1960s and originated in the community's dissatisfaction with its representation in existing microbiology societies, most notably the International Association of Microbiological Societies and the American Society for Microbiology. The society was formally founded following a meeting organized by Bernard Roizman of 40 prominent virology researchers at O'Hare International Airport in Chicago on June 9, 1981. Its first official annual meeting, organized by Milt Zaitlin, took place at Cornell University in August 1982, by which time its membership had reached almost 1,000 scientists.

The Japanese ultimately were unable to separate the idea of their new "natural" foods from the far from natural connotation of oil. These arguments were made against a background of suspicion of heavy industry in which anxiety over minute traces of petroleum was expressed. Thus, public resistance to an unnatural product led to the end of the SCP project as an attempt to solve world hunger. Also, in 1989 in the USSR, the public environmental concerns made the government decide to close down (or convert to different technologies) all 8 paraffin-fed-yeast plants that the Soviet Ministry of Microbiological Industry had by that time.

The strong attraction between these surfaces causes an extremely thin water film (a few molecules thick) to form on the mineral surface. These water molecules are much less mobile than the rest of the water in the soil, and have significant effects on soil dielectric permittivity and freezing-thawing.W.A. Jury & R. Horton, 'Soil Physics', Wiley; 6th edition (2004) In molecular biology and food science, bound water refers to the amount of water in body tissues which are bound to macromolecules or organelles. In food science this form of water is practically unavailable for microbiological activities so it would not cause quality decreases or pathogen increases.

She used a forward difference model to show that not only are bacteria significant to the biomass of these lakes, but that substantial predation occurs every season to reduce bacterial biomass by up to 88% at the height of the growing season. Further work by Takacs-Vesbach in this system included estimates of bacterioplankton organic carbon demand and respiration rates. Takacs-Vesbach also contributed to the description of the first microbiological study of sub-glacial Lake Vostok. Along with her colleagues, Takacs-Vesbach reported the presence and activity of bacteria associated with the accretion ice >4 km below the surface of the Antarctic polar plateau.

In people managed in the community, determining the causative agent is not cost- effective and typically does not alter management. For people who do not respond to treatment, sputum culture should be considered, and culture for Mycobacterium tuberculosis should be carried out in persons with a chronic productive cough. Microbiological evaluation is also indicated in severe pneumonia, alcoholism, asplenia, immunosuppression, HIV infection, and those being empirically treated for MRSA of pseudomonas. Although positive blood culture and pleural fluid culture definitively establish the diagnosis of the type of micro-organism involved, a positive sputum culture has to be interpreted with care for the possibility of colonisation of respiratory tract.

The positivist approach used in physics emphasised a strict determinism (as opposed to high probability) and led to the discovery of universally applicable laws, testable in the course of experiment. It was difficult for biology, beyond a basic microbiological level, to use this approach. Standard philosophy of science seemed to leave out a lot of what characterised living organisms - namely, a historical component in the form of an inherited genotype. Philosophers of biology have also examined the notion of “teleology.” Some have argued that scientists have had no need for a notion of cosmic teleology that can explain and predict evolution, since one was provided by Darwin.

AOAC International, informally the AOAC, was founded September 8, 1884, as the Association of Official Agricultural Chemists, by the United States Department of Agriculture (USDA), to establish uniform chemical analysis methods for analyzing fertilizers. In 1927, sponsorship was moved to the newly formed Food, Drug and Insecticide organization which become the Food and Drug Administration (FDA) in 1930. From its initial scope of analyzing fertilizer, the organization expanded the contents of its methods book to cover dairy products, pesticides, microbiological contamination and animal feeds, among others. In 1965, due to its increasing area of focus for analytical work, the name was changed to the Association of Official Analytical Chemists.

Ozone has been used in drinking water plants since 1906 where the first industrial ozonation plant was built in Nice, France. The U.S. Food and Drug Administration has accepted ozone as being safe; and it is applied as an anti-microbiological agent for the treatment, storage, and processing of foods. However, although fewer by- products are formed by ozonation, it has been discovered that ozone reacts with bromide ions in water to produce concentrations of the suspected carcinogen bromate. Bromide can be found in fresh water supplies in sufficient concentrations to produce (after ozonation) more than 10 parts per billion (ppb) of bromate — the maximum contaminant level established by the USEPA.

Chappelle developed a method using two chemicals, luciferase and luciferin, from fireflies which give off light when mixed with ATP (adenosine triphosphate), an energy storage compound found in all living cells, to detect the presence of ATP. This method for ATP detection can be used to detect life on other planets as well as microbiological organisms. Chappelle also proved that the number of bacteria in water can be measured by the amount of light given off by that bacteria. This discovery allowed scientists and doctors to detect small amounts of bacteria in places such as urine, in order to detect an onset of a bacterial infection.

The 1920s were characterized by very bad medical conditions in the Balkans. In general, based on the Kosovar health care condition and the overall public health situation, a decision was made to establish hygiene and epidemiological services in the city of Peja with the "Rockfeler" fund support from the U.S and on 5 June 1925 this service finally began to work. On the same day, basis were set for Preventive Medicine in Kosovo and 5 June is marked as a festive day for founding of the Institute of Public Health. After that date, sanitary stations, hygienic and microbiological or epidemiological services were established in Pristina, Prizren and Mitrovica.

Dental flossing of a patient by a dental health professional Beginning in 1914, Bass commenced his investigations on the understanding of Entamoeba gingivalis (Endameba buccalis) in the microbiological flora of the mouth, beginning his interest in oral health. However, it was only upon his 1940 retirement from university administrative posts that he began intensive research on dental health, a period in which he made extensive use of his experience in parasitology and microbiology. Bass focused on the understanding and prevention of the principle diseases of the mouth, particularly caries and periodontoclasia. Bass carried out extensive investigation and experimentation to determine the best means of using toothbrushes and dental floss for effective prevention of the important diseases of the mouth.

The follow-up study found that the microbiological sanitation in 2018 was even worse than before the 2008–2009 intervention. In 2014, the license of the slaughterhouse in the wet market section of Bodija Market was revoked due to unhygienic meat handling practices. In its place, the local government opened the Ibadan Central Abattoir in Amosun Village, Akinyele through public-private partnerships. The new facility is equipped with modern facilities for slaughter and processing of meat were provided in 2014 through public-private partnerships and is one of the largest abattoirs in West Africa, consisting of 15 hectares of land with stalls for 1000 meat sellers, 170 shops, administrative building, clinic, canteen, cold room, and an incinerator.

From Prelog's researches into the stereospecificity of microbiological reductions of alicyclic ketones and the enzymic oxidation of alcohols, he contributed not only to the knowledge of the mechanism of stereospecificity of enzymic reactions in general but also to the structure of the active site of the enzyme. Specifying the growing number of stereoisomers of organic compounds became for Prelog one of his important aims. In 1954 he joined R. S. Cahn and Christopher Ingold in their efforts to build a system for specifying a particular stereoisomers by simple and unambiguous descriptors that could be easily assigned and deciphered: The CIP system (Cahn-Ingold-Prelog) was developed for defining absolute configuration using "sequence rules". Together they published two papers.

When the value of corn fell in the 1920s, grass was grown instead, and sheep farmed to prepare the land for later use as orchards. By 1939 there were over 3,000 full-time employees, with offices in East Anglia as well as additional factories in Montrose, Newry and Huntingdon, and the company owned almost of farms. The company's farms were each run independently, and grew cereal and raised pedigree livestock as well as the fruit for which they were known. The Histon factory and its 2,200 employees were of added importance during the Second World War when they began to produce blackcurrant purée, following vitamin C research conducted by Mamie Olliver in the firm's microbiological laboratory in the 1930s.

Hansen's claim was weakened by his failure to produce a pure microbiological culture in an artificial medium, or to prove that the rod-shaped organisms were infectious. Further Hansen had attempted to infect at least one female patient without consent and although no damage was caused, that case ended in court and Hansen lost his post at the hospital. Hansen remained medical officer for leprosy in Norway and it was through his efforts that the leprosy acts of 1877 and 1885 were passed, leading to a steady decline of the disease in Norway from 1,800 known cases in 1875 to just 575 cases in 1901. Hansen had suffered from syphilis since the 1860s but died of heart disease.

Thus predators who eat smaller fish with the toxin in their systems may end up with much higher levels in their flesh. The influence of Corexit on microbiological communities is a topic of ongoing research.Fulmer, P. A.; Hamdan, L. J.: Effects of COREXIT EC9500A on bacterial communities influenced by the Deepwater Horizon oil spill, AGU Fall Meeting Abstracts, December 2010 Corexit 9527, considered by the EPA to be an acute health hazard, is stated by its manufacturer to be potentially harmful to red blood cells, the kidneys and the liver, and may irritate eyes and skin. Like 9527, 9500 can cause hemolysis (rupture of blood cells) and may also cause internal bleeding.

For instance, The San Jose/Santa Clara Water Pollution Control Plant instituted a water recycling program to protect the San Francisco Bay area's natural salt water marshes. The main potential risks that are associated with reclaimed wastewater reuse for irrigation purposes, when the treatment is not adequate are the following: # contamination of the food chain with microcontaminants, pathogens (i.e. bacteria, viruses, protozoa, helminths), or antibiotic resistance determinants; # soil salinization and accumulation of various unknown constituents that might adversely affect agricultural production; # distribution of the indigenous soil microbial communities; # alteration of the physicochemical and microbiological properties of the soil and contribution to the accumulation of chemical/biological contaminants (e.g. heavy metals, chemicals (i.e.

In 2009, the University of Calgary and the University of Lethbridge established the Institute for Space Imaging Science, a Canadian first. A rather imaginative recent undertaking is one by the Mars Society, an international non-profit space advocacy organization and its Canadian branch, the Mars Society of Canada, which established the Flashline Mars Arctic Research Station (FMARS) as part of their Mars Analogue Research Station Programme near the Haughton Meteor Impact Crater on Devon Island, Nunavut in 2002. Designed to develop procedures for an eventual manned mission to Mars, the "crew members" inhabit a simulated Mars base and wear simulated space suits to conduct microbiological and geological studies and simulated Mars field explorations.

An outbreak is defined as two or more cases where the onset of illness is closely linked in time (weeks rather than months) and in space, where there is suspicion of, or evidence of, a common source of infection, with or without microbiological support (i.e. common spatial location of cases from travel history). The first recognized cases of Legionnaires' disease occurred in 1976 in Philadelphia; among more than 2,000 attendees of an American Legion convention held at the Bellevue-Stratford Hotel, 182 attendees contracted the disease and 29 of them died. In April 1985, 175 people in Stafford, England, were admitted to the District or Kingsmead Stafford Hospitals with chest infection or pneumonia.

The need to further integrate these databases and to harmonize data collection, and to link the genomic data to metadata for optimal prevention of infectious diseases, was generally recognized by the scientific community. In 2011, several infectious disease control centers and other organizations took the initiative of a series of international scientific- and policy-meetings, to develop a common platform and to better understand the potentials of an interactive microbiological genomic database. The first meeting was in Brussels, September 2011, followed by meetings in Washington (March 2012) and Copenhagen (February 2013). In addition to experts from around the globe, Intergovernmental Organizations have been included in the action, notably the World Health Organization and the World Organization for Animal Health.

Many friends and colleagues concluded after his death that Meyer influenced more microbiological and epidemiological domains than any other scientist of his time; and he was driven by his deep-seated concern for the welfare of the people. He always went beyond the scientific research in order to implement practical measures of preventing and fighting the diseases. A former student and friend once put it like this: “Meyer would have won a Nobel Prize if he hadn’t worked on so many areas of discovery that nobody could keep track of all that he was doing”. He was responsible, among others, for improving laws regulating hygiene in the food industries and in public health.

To maintain the high quality of food and comply with health, safety, and environmental regulatory standards, it is best to rely on food contaminant testing through an independent third party, such as laboratories or certification companies. For manufacturers, the testing for food contaminants can minimize the risk of noncompliance in relation to raw ingredients, semi-manufactured foods, and final products. Also, food contaminant testing assures consumers safety and quality of purchased food products and can prevent foodborne diseases, and chemical, microbiological, or physical food hazards.Study finds novel method to test food for contamination The establishment of ADIs for certain emerging food contaminants is currently an active area of research and regulatory debate.

Research performed since then has shown that the concept of Blastocystis hominis as a unique species of Blastocystis infecting humans is not supported by microbiological findings. Although one species group associated with primates was found, it was also discovered that humans can acquire infection from any one of nine species groups of Blastocystis which are also carried by cattle, pigs, rodents, chickens, pheasants, monkeys, dogs, and other animals. Research has suggested that some types produce few or no symptoms, while others produce illness and intestinal inflammation. Researchers have suggested conflicting reports may be due to the practice of naming all Blastocystis from humans Blastocystis hominis and have proposed discontinuing the use of that term.

In France, the Pasteur Institute had a monopoly of specialized microbiological knowledge allowed it to raise money for serum production from both private and public sources, walking the line between a commercial pharmaceutical venture and a philanthropic enterprise. By 1933, at the depth of the Great Depression, the French wanted a welfare state to relieve distress but did not want new taxes. War veterans came up with a solution: the new national lottery proved highly popular to gamblers, while generating the cash needed without raising taxes.Nicolas Delalande, "Giving and Gambling: The Gueules Cassées, the National Lottery, and the Moral Economy of the Welfare State in 1930s France."

Marine organisms contribute significantly to the oxygen cycle, and are involved in the regulation of the Earth's climate. Shorelines are in part shaped and protected by marine life, and some marine organisms even help create new land. The United Nations Environment Programme (UNEP) has identified several areas of need in managing the global ocean: strengthen national capacities for action, especially in developing countries; improve fisheries management; reinforce cooperation in semi-enclosed and regional seas; strengthen controls over ocean disposal of hazardous and nuclear wastes; and advance the Law of the Sea. Specific problems identified as in need of attention include rising sea levels; contamination by hazardous chemicals (including oil spills); microbiological contamination; ocean acidification; harmful algal blooms; and over-fishing and other overexploitation.

121, 138 In 1959, for controversial reasons, Butlin's group was disbanded and its staff and collection redeployed. Postgate was released to take a post at the Microbiological Research Establishment (MRE), part of the Porton Down research complex at Porton near Salisbury in Wiltshire, to undertake fundamental research on how bacteria survive mild stresses such as near starvation, using both continuous and synchronous culture of bacteria. His extensive paper on the survival of starvation by klebsiella bacteria reopened a research topic largely dormant since the 1920s and introduced the concept of cryptic growth (a sort of necrophagy) in the persistence of bacterial populations in ancient isolated environments such as salt inclusions or fossils. He was promoted Senior Principal Scientific Officer in 1961.

Qualified Through Verification (QTV), one of the United States Department Of Agriculture process verification programs, enables those in the processed fruit and vegetable industry to gain official certification of the wholesomeness of their products to improve marketing opportunities. Under this voluntary, fee-for-service program, AMS, using HACCP-based principles, first inspects the company’s facilities to ensure they are properly designed, are consistent with the Food and Drug Administration’s good manufacturing practices, have on-site microbiological testing, follow accepted sanitary operating procedures, and so forth. Ongoing monitoring, including periodic unannounced site visits, sampling, and audits by AMS are intended to ensure that the firm maintains its QTV status, which then authorizes it to use an official AMS mark, the QTV shield, on product labels and in advertisements.

Thermal immersion circulator A thermal immersion circulator is an electrically powered device that circulates and heats a warm fluid kept at an accurate and stable temperature. It is used in process, environmental, microbiological, hazardous waste, and other laboratories. Since the late twentieth century, they have also been used for sous-vide food cooking, a method that uses airtight plastic bags in a water bath at accurately regulated temperatures much lower than usually used for cooking. A thermal immersion circulator comprises a circulator pump or motorized impeller to move the fluid, a heating element immersed in the fluid, an accurate temperature probe, and control circuitry which compares the measured temperature with the desired value and supplies power to the heater as required to stabilize the temperature.

The gold standard of diagnosis is microbiological isolation of N. meningitidis by growth from a sterile body fluid, which could be CSF or blood. Diagnosis is confirmed when the organism has grown, most often on a chocolate agar plate, but also on Thayer-Martin agar. To differentiate any bacterial growth from other species a small amount of a bacterial colony is tested for oxidase, catalase for which all clinically relevant Neisseria show a positive reaction, and the carbohydrates maltose, sucrose, and glucose, in which N. meningitidis will ferment that is, utilize the glucose and maltose. Finally, serology determines the subgroup of the N. meningitidis, which is important for epidemiological surveillance purposes; this may often only be done in specialized laboratories.

One of the major responsibilities of HFSO was the scientific risk assessment relating to food safety, taking into account up-to-date scientific findings of recognised international institutions. The scientific risk assessment is based on identifying potential hazards, defining their characteristics, assessing their incidence and frequency and describing the risk. HFSO is responsible for assessing risks relating to concrete events, furthermore by analysing the data of annual official inspections concerning various agricultural, technological, environmental and biological contaminants, pesticide residues and natural toxic substances in raw and processed food. Based on the risk assessment, it forwards a proposal concerning the priority of inspections in the forthcoming period and participates in international risk assessment projects relating to individual chemical and microbiological contaminants.

Geochemists working in the field, office, lab, or classroom store their analyses, calculate the distribution of chemical mass, create plots and diagrams, evaluate their experiments, and solve real-world problems. The software is used by environmental chemists, engineers, microbiologists, and remediators to gain quantitative understanding of the chemical and microbiological reactions which control the fate and mobility of contaminants in the biosphere. With this knowledge, they can develop predictive models of contaminant fate and transport, and test the effectiveness of costly remediation schemes before implementing them in the field. Within the energy industry, petroleum engineers, mining geologists, environmental geochemists and geothermal energy developers use the software to search for resources, optimize recovery, and manage wastes, all while using safe and environmentally friendly practices.

Quantitative microbiological risk assessments (QMRAs) combine pathogen concentrations in water with dose-response relationships and data reflecting potential exposure to estimate the risk of infection. Data on water exposure are generally collected using questionnaires, but may also be determined from actual measurements of water ingested, or estimated from previously published data. Respondents are asked to report the frequency and timing and location of exposures, detailed information about the amount of water swallowed and head submersion, and basic demographic characteristics such as age, gender, socioeconomic status and family composition. Once sufficient data are collected and determined to be representative of the general population, they are usually fit with distributions, and these distribution parameters are then used in the risk assessment equations.

The office of Public Analyst was established in 1860, with the Act for Preventing the Adulteration of Articles of Food and Drink, the first three appointments being in London, Birmingham and Dublin. The first Scottish analyst was Henry Littlejohn in Edinburgh in 1862, who, with a strong medicinal background and brilliant mind, established many of the critical foundations of public analysis. Since the separation of the UK and Ireland, they operate under different legislation, but the term and general duties are the same. The original work was chemical testing, and this is still a major part, but nowadays microbiological examination of food is an important activity, particularly in Scotland, where Public Analyst laboratories also carry out a statutory Food Examiner role.

Microbiological sources of exoenzymes including amylases, proteases, pectinases, lipases, xylanases, cellulases among others are used for a wide range of biotechnological and industrial uses including biofuel generation, food production, paper manufacturing, detergents and textile production. Optimizing the production of biofuels has been a focus of researchers in recent years and is centered around the use of microorganisms to convert biomass into ethanol. The enzymes that are of particular interest in ethanol production are cellobiohydrolase which solubilizes crystalline cellulose and xylanase that hydrolyzes xylan into xylose. One model of biofuel production is the use of a mixed population of bacterial strains or a consortium that work to facilitate the breakdown of cellulose materials into ethanol by secreting exoenzymes such as cellulases and laccases.

The Chinese water quality standard for reuse corresponds to the Chinese surface water quality standard III (suitable for aquaculture and recreational purposes). It is apparently less strict than effluent standards in the US that correspond to the more stringent Chinese national surface water quality standard II. Another source lists in detail standards for four types of non-potable municipal uses (toilet flushing, road cleaning/firefighting, car washing and construction) as well as landscaping, clearly showing that there is more than one standard for reclaimed water in Beijing. The microbiological standards for the various uses are the same, but the standards in terms of turbidity and dissolved solids vary depending on the intended use. As of 2011, 100 residential communities used reclaimed water in toilet flushing.

Engaged in research work on immunology and the effects of the administering of toxins via aerosols at the Lister Institute's Serum Department at Elstree, by summer of 1940 Henderson was to find himself seconded to the Ministry of Supply and working between the Lister Institute and the government's Chemical Defence Experimental Establishment, at Porton Down in Wiltshire. In October 1940, on the instruction of the War Council a team of microbiologists was assembled, including David Henderson, to research use and protection against bacterial agents under the leadership of Paul Fildes. It was initially known as the Biology Department, Porton (BDP) and would later become the autonomous Microbiological Research Establishment. The same year Henderson was awarded a DSc degree by the University of London.

Microbiological cultures can be grown in petri dishes of differing sizes that have a thin layer of agar-based growth medium. Once the growth medium in the petri dish is inoculated with the desired bacteria, the plates are incubated at the optimal temperature for the growing of the selected bacteria (for example, usually at 37 degrees Celsius, or the human body temperature, for cultures from humans or animals, or lower for environmental cultures). After the desired level of growth is achieved, agar plates can be stored upside down in a refrigerator for an extended period of time to keep bacteria for future experiments. There are a variety of additives that can be added to agar before it is poured into a plate and allowed to solidify.

Major post-war science facilities were closed down during this period, notably the Algonquin Park Radio Observatory and the tokamak reactor. In spite of cutbacks, a number of big new science projects were realized, including the Canadian Astronaut Programme, the Sudbury Neutrino Observatory in Sudbury, Ontario, the National Microbiological Laboratory in Winnipeg, the Canadian Light Source Synchrotron at the University of Saskatoon in Saskatoon, Saskatchewan and the National Institute for Nanotechnology in Edmonton, Alberta. At the beginning of the 21st century, due to financial restraints, token funding efforts were made to give Canada a place with the construction and operation of the Gemini astronomical telescopes and the Large Hadron Collider in Geneva. Canada's participation in the international fusion reactor project was cancelled.

A single spore viewed with a transmission electron microscope, purportedly showing a detached inner capsule. Initially, the Centre for Earth Science Studies (CESS) stated that the likely cause of the red rain was an exploding meteor, which had dispersed about 1,000 kg (one ton) of material. A few days later, following a basic light microscopy evaluation, the CESS retracted this as they noticed the particles resembled spores, and because debris from a meteor would not have continued to fall from the stratosphere onto the same area while unaffected by wind. A sample was, therefore, handed over to the Tropical Botanical Garden and Research Institute (TBGRI) for microbiological studies, where the spores were allowed to grow in a medium suitable for growth of algae and fungi.

Dry ice blasting can be used to clean food processing equipment. As early as 2004, the UK Food Standards Agency documented the process to effectively decontaminate surfaces of Salmonella enteritidis, E. coli, and Listeria monocytogenes such that these microorganisms are not detectable using conventional microbiological methods.Food Standards Agency Report, Microchem Bioscience Limited, 19 September 2004 "As a result of two outbreaks salmonellosis associated with the consumption of peanut butter and baby food in 2006-2007, an effort was taken" by GMA members such as Cargill "to reassess industry practices for eliminating salmonella in low-moisture products" because "Salmonella outbreaks from low- moisture products are relatively rare but often impact large numbers of people." A document resulted from this effort entitled "CONTROL OF SALMONELLA IN LOW-MOISTURE FOODS".

From 2008 to 2009, a group of food safety researchers launched an initiative working with a small group of butchers in the wet market section of Bodija Market to promote positive food safety practices and peer-to-peer training. The initiative led to 20% more meat samples being of acceptable quality. A follow-up study in 2019 on the same group of butchers found that, while many of the butchers still remembered the food safety practices, "none of the butchers reported that they continued to buy and replace the materials after the exhaustion of those distributed during the intervention programme". The follow-up study found that the microbiological sanitation in 2018 was even worse than before the 2008–2009 intervention.

She developed a microbiological culture system that mimics the normal conditions of community formation to reconstruct and manipulate the interactions between species in these communities, identifying widespread bacterial-fungal interactions. She uses these cultures to investigate the genetic requirements for community interactions and how horizontal gene transfer affects the genetic makeup of species in these communities. Dutton collaborates widely with chefs and cheesemakers, and has appeared in the Netflix documentary Cooked, (episode 4) the PBS documentary series The Mind of a Chef, (season 1, episode 2), and on the podcasts Science Friday and Meet the Microbiologist. In 2015 Dutton moved to the University of California, San Diego, where she is an assistant professor in the Division of Biological Sciences, Section on Molecular Biology.

The genitourinary system appears to have a microbiota, which is an unexpected finding in light of the long-standing use of standard clinical microbiological culture methods to detect bacteria in urine when people show signs of a urinary tract infection; it is common for these tests to show no bacteria present. It appears that common culture methods do not detect many kinds of bacteria and other microorganisms that are normally present. As of 2017, sequencing methods were used to identify these microorganisms to determine if there are differences in microbiota between people with urinary tract problems and those who are healthy. To properly assess the microbiome of the bladder as opposed to the genitourinary system, the urine specimen should be collected directly from the bladder, which is often done with a catheter.

Antibiotics are generally reserved for severe infections, in which there is facial swelling, systemic upset and elevated temperature. Since periodontal abscesses frequently involve anaerobic bacteria, oral antibiotics such as amoxicillin, clindamycin (in penicillin allergy or pregnancy) and/or metronidazole are given. Ideally, the choice of antibiotic is dictated by the results of microbiological culture and sensitivity testing of a sample of the pus aspirated at the start of any treatment, but this rarely occurs outside the hospital setting. Other measures that are taken during management of the acute phase might include reducing the height of the tooth with a dental drill, so it no longer contacts the opposing tooth when biting down; and regular use of hot salt water mouth washes (antiseptic) that encourages further drainage of the infection.

The AIT was created in 1978 for purposes of contingency air evacuation of a hypothetical USAMRIID researcher who might become exposed to a highly infectious pathogen while undertaking endemic surveillance in remote areas of the world where a suspected or known disease outbreak was occurring. At the core of AIT operations was its specialized equipment, notably the Aircraft Transit Isolator (ATI). Developed by Vickers in the U.K. in the 1970sClayton, A.J., “Containment aircraft transit isolator”; Aviat Space Environ Med, 1979: Oct;50(10):1067-72. — and manufactured in later years by Elwyn Roberts Isolators, Shropshire, UK, until 2007 — the ATI was a self-contained unit capable of transporting a patient with a highly virulent disease and at the same time providing maximum microbiological security while full nursing care and treatment are rendered.

Nichrome wire is commonly used in ceramic as an internal support structure to help some elements of clay sculptures hold their shape while they are still soft. Nichrome wire is used for its ability to withstand the high temperatures that occur when clay work is fired in a kiln. Nichrome wire can be used as an alternative to platinum wire for flame testing by colouring the non-luminous part of a flame to detect cations such as sodium, potassium, copper, calcium, etc. Other areas of usage include motorcycle mufflers, in certain areas in the microbiological lab apparatus, as the heating element of plastic extruders by the RepRap 3D printing community, in the solar panel deployment mechanism of spacecraft LightSail-A, and as the heating coils of electronic cigarettes.

January 2002 The Walkerton Report, Part One, described events in the community and a series of failures, both human and systemic, that led to contamination of the water supply. The report made recommendations based on the circumstances of the outbreak. It estimated that the Walkerton water contamination cost a minimum of C$64.5–155 million and laid much of the blame at the door of the Walkerton Public Utilities Commission: > The Walkerton Public Utilities Commission operators engaged in a host of > improper operating practices, including failing to use adequate doses of > chlorine, failing to monitor chlorine residuals daily, making false entries > about residuals in daily operating records, and misstating the locations at > which microbiological samples were taken. The operators knew that these > practices were unacceptable and contrary to Ministry of Environment > guidelines and directives.

Neither of these recommendations was implemented as conditions of operation when Well 5 received a Certificate of Approval in 1979. Multiple subsequent tests on the well between 1979 and 2000 continued to conclude that due to the shallow depth at which Well 5 was drilled and the tendency of its water level and makeup to be directly affected by surface runoff, caution toward contamination levels in the well was advisable. Wells 6 and 7 were drilled more deeply and drew from areas of land with significantly less fractured bedrock than well 5. In 2000, Ontario law indicated that in a community the size of Walkerton, at least thirteen water samples per month should be submitted for microbiological testing, with the samples being drawn from "the point at which the treated water enters the distribution system".

Service by Emergency Rider Volunteers, or SERV, is the name used by a number of blood bike charities based in England, whose volunteers provide a motorcycle courier service, free of charge, to the National Health Service and the air ambulance charities. The original SERV group was established in 1981. Charities that use the SERV name operate across England: SERV Surrey & South London, SERV Sussex, SERV Kent, SERV Ox Bucks Berks and Northants, SERV Suffolk and Cambridge, SERV Norfolk, SERV Wessex, SERV Herts & Beds. Their volunteers work outside normal office hours and use either their own or the charity's dedicated response motorcycles to transport items such as blood for transfusion, blood samples for pathological or microbiological analysis, drugs, patient notes, x-rays, scans, medical equipment, samples, vaccines and donated human breast milk.

In Moscow, Alibek began his service as Deputy Chief of the Biosafety Directorate at Biopreparat. He was later promoted (1988) to First Deputy Director of Biopreparat, where he not only oversaw the biological weapons facilities but also the significant number of pharmaceutical facilities that produced antibiotics, vaccines, sera, and interferon for the public. In response to a Spring 1990 announcement that the Ministry of Medical and Microbiological Industry was to be reorganized, Alibek drafted and forwarded a memo to General Secretary Mikhail Gorbachev proposing the cessation of Biopreparat's BW work. Though Gorbachev approved the proposal, an additional paragraph had been secretly inserted into Alibek's draft, resulting in a presidential decree that ordered the end of Biopreparat's BW work but also required them to remain prepared for future production.

VCC calibration curves The method of enumeration of surviving cells used by VCC is termed quantitative growth kinetics (QGK). It relates the kinetic time taken for the turbidity of a bacterial batch microbiological culture in a well of a 96-well microplate to reach a threshold difference in turbidity to a 10-fold dilution series of calibration growth curves. Quantification of the number of viable cells is done using a process mathematically identical to quantitative real-time polymerase chain reaction (QPCR), except with QGK cells, rather than copies of PCR products, grow exponentially. The time taken to reach the threshold is called the "threshold time", Tt, which is equivalent to the QPCR value "cycle time" or Ct. There are at least five processes that cause delays in threshold times in VCC assays: 1\.

CIEA has developed animal experimentation systems based on the concept "scientific animal experiments with reproducible results can not be achieved unless the experiments are performed ethically with the animals maintained in a normal state." To this end, the 3R (Replacement, Refinement, and Reduction of Animals in Research) principle proposed by Russell and Burch in 1959 was adopted. By using animals under strict quality control and controlling the environment so that the animals are not subjected to stress, it is possible to reduce the number of animals used in experiments (Reduction among the 3Rs). It is also possible to prevent infections such as mouse hepatitis or Sendai virus through periodic monitoring of the microbiological status of animals for early diagnosis and quality assurance and to minimize discomfort of the animals (Refinement).

Reagents used for Lancefield grouping Lancefield grouping is a system of classification that classifies catalase-negative Gram-positive cocci based on the carbohydrate composition of bacterial antigens found on their cell walls. The system, created by Rebecca Lancefield, was historically used to organize the various members of the family Streptococcaceae, which includes the genera Lactococcus and Streptococcus, but now is largely superfluous due to explosive growth in the number of streptococcal species identified since the 1970s. However, it has retained some clinical usefulness even after the taxonomic changes, and as of 2018, Lancefield designations are still often used to communicate medical microbiological test results in the United States. Enterococcus, formerly known as Group D Streptococcus, were classified as members of the genus Streptococcus until 1984 and were included in the original Lancefield grouping.

A synchronous or synchronized culture is a microbiological culture or a cell culture that contains cells that are all in the same growth stage. As numerous factors influence the cell cycle (some of them stochastic) normal cultures have cells in all stages of the cell cycle. Obtaining a culture with a unified cell-cycle stage is useful for biological research where a particular stage in the cell cycle is desired (such as the culturing of parasitized cells). Since cells are too small for certain research techniques, a synchronous culture can be treated as a single cell; the number of cells in the culture can be easily estimated, and quantitative experimental results can simply be divided in the number of cells to obtain values that apply to a single cell.

MALDI-TOF spectra are often used for the identification of micro-organisms such as bacteria or fungi. A portion of a colony of the microbe in question is placed onto the sample target and overlaid with matrix. The mass spectra of expressed proteins generated are analyzed by dedicated software and compared with stored profiles for species determination in what is known as biotyping. It offers benefits to other immunological or biochemical procedures and has become a common method for species identification in clinical microbiological laboratories.. Benefits of high resolution MALDI-MS performed on a Fourier transform Ion cyclotron Resonance mass spectrometry (also known as FT-MS) have been demonstrated for typing and subtyping viruses though single ion detection known as proteotyping, with a particular focus on influenza viruses.

The program was established in 1991 by three international organizations: the United Nations Educational, Scientific and Cultural Organization (UNESCO), the Scientific Committee on Problems of the Environment (SCOPE) and the International Union of Biological Science (IUBS), at the time the need to address the complex scientific questions posed by the loss of and change in global biodiversity was identified. The goal of the initiative was to develop an international, non-governmental umbrella programme for research projects. In 1996, the program welcomed two new sponsors, the International Council for Science (ICSU) and the International Union of Microbiological Societies (IUMS). The key findings during its first decade were synthesised in a series of books and laid the groundwork for experimental and theoretical research carried out by the program and the International Geosphere-Biosphere Programme (IGBP).

Disease, for example, which is difficult to comprehend on both large and microbiological scales, is often communicated through metaphor and analogy. When a public health campaign “wages war” on cancer, or a microbiologist describes a virus as “attacking” a cell, these forceful words create a war-like metaphor for understanding the way disease works. Notable work in this area has been done by Judy Segal, who chronicled the impact of five biomedical metaphors in her book Health and the Rhetoric of Medicine, including ‘‘medicine is war,’’ ‘‘the body is a machine,’’ ‘‘diagnosis is health,’’ ‘‘medicine is a business,’’ and ‘‘the person is genes, ’’ all of which have had academic, cultural, and social impacts on the way medicine is practiced and understood.See biomedical metaphors in Segal, Judy Z.

A small quantity of tissue is sampled from the liver when doing a biopsy, which is then examined under a microscope Liver biopsies may be taken percutaneously (via a needle through the skin), transvenously (through the blood vessels), endoscopically (through endoscopic ultrasound fine needle biopsy), or directly during abdominal surgery. The sample is examined by microscope, and may be processed further by immunohistochemistry, determination of iron and copper content, and microbiological culture if tuberculosis is suspected For a percutaneous biopsy, it is recommended to use a Birmingham gauge 16 or wider cutting needle, and obtaining a length of 20–25 mm of liver tissue. The presence of 10–12 portal tracts within the specimen is considered sufficient for reliable analysis, ensuring that architectural relationships between structures are maintained.

Bacteria and viruses are the most commonly monitored groups of microbiological organisms and even these are only of great relevance where water in the aquatic environment is subsequently used as drinking water or where water contact recreation such as swimming or canoeing is practised. Although pathogens are the primary focus of attention, the principal monitoring effort is almost always directed at much more common indicator species such as Escherichia coli, supplemented by overall coliform bacteria counts. The rationale behind this monitoring strategy is that most human pathogens originate from other humans via the sewage stream. Many sewage treatment plants have no sterilisation final stage and therefore discharge an effluent which, although having a clean appearance, still contains many millions of bacteria per litre, the majority of which are relatively harmless coliform bacteria.

For genotyping of microorganisms for medical diagnosis, or other purposes, scientists may use a wide variety of DNA profiling techniques, such as polymerase chain reaction, pulsed-field gel electrophoresis or multilocus sequence typing. A complication of this broad variety of techniques is the difficulty to standardize between techniques, laboratories and microorganisms, which may be overcome using the complete DNA code of the genome generated by whole genome sequencing. For straightforward diagnostic identification, the whole genome sequencing information of a microbiological sample is fed into a global genomic database and compared using BLAST procedures to the genomes already present in the database. In addition, whole genome sequencing data may be used to back calculate to the different pre- whole genome sequencing genotyping methods, so previous collected valuable information is not lost.

Early diagnosis is the key to survival of the patients, but the diagnosis of the disease is hard due to difficulties in stimulating sporulation. Furthermore, there has been only 38 cases of infections reported as of 2012 and the author of the paper suggested that low number of cases reported can be due to lack of awareness of this species in clinical environment, high mortality rate, and largely, microbiological and clinical bias resulted from difficulties in stimulating sporulation of this species. To ease the identification of fungus producing sterile mycelium such as S. vasiformis and A. elegans, exoantigen test has been developed. For S. vasiformis, even though exoantigen testing is helpful with positive test, it is rarely used because of the high false-negative rate, requiring confirmation by sporulating morphology with all the negative tests.

Simple procedures such as boiling or the use of a household activated carbon filter are not sufficient for treating all possible contaminants that may be present in water from an unknown source. Even natural spring water – considered safe for all practical purposes in the 19th century – must now be tested before determining what kind of treatment, if any, is needed. Chemical and microbiological analysis, while expensive, are the only way to obtain the information necessary for deciding on the appropriate method of purification. According to a 2007 World Health Organization (WHO) report, 1.1 billion people lack access to an improved drinking water supply; 88% of the 4 billion annual cases of diarrheal disease are attributed to unsafe water and inadequate sanitation and hygiene, while 1.8 million people die from diarrheal disease each year.

It is now recognized and accepted by an increasing number of regulators that the microbiological risks of grey water reuse at the single dwelling level where inhabitants already had intimate knowledge of that grey water are in reality an insignificant risk, when properly managed without the need for onerous approval processes. This is reflected in the New South Wales Government Department of Water and Energy's newly released grey water diversion rules, and the recent passage of grey water legislation in Montana. 2007 grey water legislation in Montana In the 2009 Legislative Session, the state of Montana passed a bill expanding grey water use into multi-family and commercial buildings. The Department of Environmental Quality has already drafted rules and design guidelines for grey water re-use systems in all these applications.

In the early 1990s, Ben-Jacob's group discovered two pattern-forming bacteria species—the Paenibacillus dendritiformis and the Paenibacillus vortex (see also Paenibacillus). Combining microbiological experiments with physical principles of self-organization and advanced modeling, Ben-Jacob advanced the recognition that bacteria are smart cooperative organisms that employ advanced communication to lead intricate social lives in large and complex colonies. Sophisticated chemical communication allows bacteria to rapidly adapt to changes in the environment, distribute tasks, "learn from experience", make decisions and prepare for the future. Ben-Jacob put forward the idea of bacterial social intelligence and his group devised a social IQ score of bacteria as a comparative genomic tool to assess the genome potential of bacteria to conduct successful cooperative and adaptable behaviors, or social behaviors, in complex environments.

Soil conditioners may be used to improve water retention in dry, coarse soils which are not holding water well. The addition of organic material for instance can greatly improve the water retention abilities of sandy soils and they can be added to adjust the pH of the soil to meet the needs of specific plants or to make highly acidic or alkaline soils more usable. The possibility of using other materials to assume the role of composts and clays in improving the soil was investigated on a scientific basis earlier in the 20th century, and the term soil conditioning was coined. The criteria by which such materials are judged most often remains their cost- effectiveness, their ability to increase soil moisture for longer periods, stimulate microbiological activity, increase nutrient levels and improve plant survival rates.

Polybius wrote that Hannibal had crossed the highest of the Alpine passes: Col de la Traversette, between the upper Guil valley and the upper Po river is the highest pass. It is moreover the most southerly, as Varro in his De re rustica relates, agreeing that Hannibal's Pass was the highest in Western Alps and the most southerly. Mahaney et al. argue that factors used by De Beer to support Col de la Traversette including "gauging ancient place names against modern, close scrutiny of times of flood in major rivers and distant viewing of the Po plains" taken together with "massive radiocarbon and microbiological and parasitical evidence" from the alluvial sediments either side of the pass furnish "supporting evidence, proof if you will" that Hannibal's invasion went that way.

According to McNeill's Law, the microbiological aspect of conquest and invasion has been the deciding principle or one of the deciding principles in both the expansion of certain empires (as during the emigration to the Americas) and the containment in others (as during the crusades). The argument is that less civilized peoples were easily subjugated due to the immunological advantages of those coming from civilized countries. An evidence presented to support the hypothesis involves the manner diseases associated with Europeans were rebuffed in their forays into disease-experienced countries such as China and Japan. McNeill's law also maintains that parasites are not only natural but also social in the sense that these organisms are part of the social continuum and that the human social evolution is inextricably linked with genetic transformations.

Particularly hard-hit by heavy water are the delicate assemblies of mitotic spindle formations necessary for cell division in eukaryotes. Plants stop growing and seeds do not germinate when given only heavy water, because heavy water stops eukaryotic cell division. The deuterium cell is larger and is a modification of the direction of division.Crespi, H., Conrad, S., Uphaus, R., Katz, J. (1960) Cultivation of Microorganisms in Heavy Water, Annals of the New York Academy of Sciences, Deuterium Isotopes in Chemistry and Biology, pp. 648–666.Mosin, O. V., I. Ignatov, I.

Molecular diagnostic assays provide a fairly cost-effective and rapid (about <2hours of turnaround time) means to diagnose the most common infections. However, nearly all conventional microbiological tests in current use detect only one or a limited panel of pathogens at a time or require that a microorganism be successfully cultured from a clinical sample. By contrast, while NGS assays in current use cannot compare with conventional tests with respect to speed (the sequencing run alone on a standard Illumina instrument takes >18hours) mNGS could enable a broad range of pathogens (virus, bacteria, fungi and/or parasites) to be identified from culture or directly from clinical samples on the basis of uniquely identifiable DNA and/or RNA sequences. To date, several studies have provided a glimpse into the promise of NGS in clinical and public health settings.

From the first identification of a bacterial species in 1872, microbial species were named according to the binomial nomenclature, based on largely subjective descriptive characteristics. By the end of the 19th century, however, it was clear that this nomenclature and classification system required reform. Although several different comprehensive nomenclature systems were invented (most notably, that described in Bergey's Manual of Determinative Bacteriology, first published in 1923), none gained international recognition. In 1930, a single international body, now named the International Committee on Systematics of Prokaryotes (ICSP), was established to oversee all aspects of prokaryotic nomenclature. Work began in 1936 on drafting a Code of Bacteriological Nomenclature, the first version of which was approved in 1947. In 1950, at the 5th International Congress for Microbiology, a journal was established to disseminate the committee's conclusions to the microbiological community.

They arrive at the planet Alpha, which orbits Alpha Centauri and is all ocean except for an island 250 km long and 65 km wide on which live a small group of humans. In a reference to the radioactive Earth of Asimov's novel Pebble in the Sky, the restoration of Earth's soil was eventually abandoned in favour of resettling the population to "New Earth", which the First Galactic Empire had already been terraforming. The natives appear friendly, but secretly intend to kill the visitors with a microbiological agent, to prevent them from informing the rest of the galaxy of their existence. They are warned to escape before the agent can be activated, by a native woman who has formed an attraction to Trevize and was impressed by Fallom's ability to play a flute with just her mind.

Since 2002, Dr. Siqueira is the Chairman of Endodontics, Director of the Postgraduate Program in Endodontics and Head of the Molecular Microbiology laboratory at Estácio de Sá University, in Rio de Janeiro, Brazil. Dr. Siqueira has made important contributions to the field of Endodontics, specially working with microbiological issues. Along with his colleague Dr. Isabela Rôças, he developed several studies using molecular biology methods that helped to decipher the diversity of the microbiota infecting dental root canals. They were pioneers in the use of several molecular techniques to unravel the identity of endodontic pathogens. They for the first time detected several oral pathogens in association with apical periodontitis and abscesses, including Treponema denticola (year 2000), Treponema socranskii (year 2001), other treponemes (years 2003-2008), Filifactor alocis (year 2003), Synergistetes species and many other cultivable and uncultivated species/phylotypes.

In a liquid medium with few or no expected organisms, from an area that is normally sterile (such as CSF, blood inside the circulatory system) centrifugation, decanting the supernatant and using only the sediment will increase the chance to grow and isolate bacteria or the usually cell-associated viruses. If one expects or looks for a particularly fastidious organism, the microbiological culture and isolation techniques will have to be geared towards that microbe. For example, a bacterium that dies when exposed to air, can only be isolated if the sample is carried and processed under airless or anaerobic conditions. A bacterium that dies when exposed to room temperature (thermophilic) requires a pre-warmed transport container, and a microbe that dries and dies when carried on a cotton swab will need a viral transport medium before it can be cultured successfully.

In the field, oil is moved through pipelines from about 1000 wells, to a pumping station at the head of the Trans-Alaska Pipeline; "flow lines" carry oil from the wells to local processing centers where the oil is prepared for long-range transport through the pipeline by removing water and gas; "transit lines" then carry the oil to the pumping station.International Mapping on behalf of BP. BP in Alaska, animated map There are about 8 miles of transit line in the Western Operating Area, connecting Gathering Center 2 (at the western end of the line) to Gathering Center 1, and then running to the pumping station, where the transit line ends. Oil transit lines must be regularly cleaned and inspected for corrosion. Corrosion inhibitor chemicals are added to the flow to discourage the growth of bacteria which cause microbiological corrosion.

Yersin, after his research with Roux, abruptly left the Institute for personal reasons, without losing Pasteur's benevolence, who never doubted that the young man was destined to great things in the scientific area and would contribute in spreading Pasteur's discoveries around the world. The news of a violent plague outburst in Yunman enabled Yersin to truly show and reach his potential as he was summoned, as Pasteur's scholar, to conduct a microbiological research of the disease. The plague he had to deal with was the bubonic plague, which is recognizable most of the time through the abscesses, known as buboes, it provokes in its victims. Yersin looked for the germ responsible for the infection specifically in these plague-spots, tumors caused by the inflammation of the lymphatic glands which become black because of the necrosis of the tissue.

Originally working in cooperation with Dr. David Stahl, Rittmann introduced the powerful tools of molecular biology to environmental engineering, helping create the exciting field known today as Environmental Biotechnology, in which the goal is to manage microbial communities so that they provide services to society. The tools of molecular microbial ecology directly interrogate the genetic information in microorganisms. They make it possible to determine what types of microorganisms are present in the complex communities of environmental biotechnologies, what reactions those microorganisms can carry out, what reactions they are carrying out, and how they interact with each other and their environment. Now working hand-in-glove with Center colleague Dr. Rosa Krajmalnik-Brown, Rittmann is using molecular microbial ecology to understand and manage microbial communities in a wide range of microbiological processes used for removing pollution from water, generating renewable resources, and improving human health.

Joye's research on the 2010 Deepwater Horizon oil spill received extensive media coverage and she continues to be a source for the media regarding the microbiological processing of hydrocarbons in the environment, the dynamics of extreme environments, and general oceanography. She has been interviewed, quoted, or featured in numerous news stories about her research in the Gulf of Mexico, including interviews by The New York Times, The Wall Street Journal, Discover, Science and Nature. Joye's media appearances helped educate the media and general public about unique features of the Deepwater Horizon, including the deepwater plumes, marine oil snow and oil sedimentation, and the application of chemical dispersants, as well as highlighting the valuable ecosystem services provided by the Gulf's deepwater ecosystems. The Deepwater Horizon oil spill was an enormous environmental perturbation but it was also an opportunity to teach the public about the Gulf Ecosystem and the ocean in general.

This perspective is what gave Margaret and Warren Lewis their place in the Department of Embryology at the Carnegie Institution. With so many avenues opened by cell culture to explore, Margaret Lewis and her husband diverged in their area of study, with Margaret Lewis choosing to focus on microbiological problems, which involved close observations of chick embryo intestines reacting to typhoid bacilli in the medium in which it was grown. Through the tissue culture techniques the Lewises had developed, these studies showed that infections and diseases were cellular phenomena in that infection was observed in an isolated system but the events occurred in a way that would be observed in an organism as a whole. In her work with chick embryos, Margaret Lewis studied connective tissue formation within the tissues as well as outside of an environment where factors involved in coagulation are present.

With the additional lifting capability presented by the Space Shuttle program, NASA designers were able to create a more comprehensive medical readiness kit. The SOMS consists of two separate packages: the Medications and Bandage Kit (MBK) and the Emergency Medical Kit (EMK). While the MBK contained capsulate medications (tablets, capsules, and suppositories), bandage materials, and topical medication, the EMK had medications to be administered by injection, items for performing minor surgeries, diagnostic/therapeutic items, and a microbiological test kit. John Glenn, the first American astronaut to orbit the Earth, returned with much fanfare to space once again on STS-95 at 77 years of age to confront the physiological challenges preventing long-term space travel for astronauts—loss of bone density, loss of muscle mass, balance disorders, sleep disturbances, cardiovascular changes, and immune system depression—all of which are problems confronting aging people as well as astronauts.

In January 1946 Henderson had succeeded Fildes at Porton Down as Director of the renamed Microbiological Research Department and an advisory panel had been assembled by the Ministry of Supply under the chairmanship of Maurice Hankey. Under Henderson's direction new laboratories at Porton Down were built between 1948 and 1951 and these and the work done there by Henderson and his team gained an international reputation in microbiology, recognised in the award to Henderson of the CB in 1957 and his election to the Royal Society in 1959, in which year the Ministry of Supply was dissolved and Henderson's department was to come within the remit of the War Office. David Henderson was a founding member of the Society for General Microbiology, a member of its committee from 1947 to 1951, and in 1963 was elected its President. He wrote and co-wrote numerous published scientific papers during his career.

Originally developed for cleaning closed systems as described above, CIP has more recently been applied to groundwater source boreholes used for high end-uses such as natural mineral / spring waters, food production and carbonated soft drinks (CSD). Boreholes that are open to the atmosphere are prone to a number of chemical and microbiological problems, so sources for high end-use are often sealed at the surface (headworks). An air filter is built into the headworks to permit the borehole to inhale and exhale when the water level rises and falls quickly (usually due to the pump being turned on and off) without drawing in airborne particles or contaminants (spores, molds, fungi, bacteria, etc.). In addition, CIP systems can be built into the borehole headworks to permit the injection of cleaning solutions (such as sodium hypochlorite or other sanitizers) and the subsequent recirculation of the mix of these chemicals and the groundwater.

Up to 25% of patients with TB of the lymph nodes (TB lymphadenitis) will get worse on treatment before they get better and this usually happens in the first few months of treatment. A few weeks after starting treatment, lymph nodes often start to enlarge, and previously solid lymph nodes may soften and develop into tuberculous cervical lymphadenitis. This should not be interpreted as failure of therapy and is a common reason for patients (and their physicians) to panic unnecessarily. With patience, two to three months into treatment the lymph nodes start to shrink again and re- aspiration or re-biopsy of the lymph nodes is unnecessary: if repeat microbiological studies are ordered, they will show the continued presence of viable bacteria with the same sensitivity pattern, which further adds to the confusion: physicians inexperienced in the treatment of TB will then often add second-line drugs in the belief that the treatment is not working.

After graduation in Bologna in 1947, De Rosa started teaching in 1966 at the Istituto Sperimentale di Enologia in Conegliano, (formerly part of the Scuola Enologica di Conegliano), that he lately directed for several years, the most relevant titles among his wide bibliography include the classic handbooks Tecnologia dei Vini Bianchi (White Wines Production Technology), Tecnologia dei Vini Spumanti (Sparkling Wines Production Technology), Tecnologia dei Vini Rossi (Red Wines Production Technology) and Tuttovini (translated in several languages), and the collection of autobiographical novels Andar Per Vini that in the 1970 first edition was accompanied by illustrations by the Italian artist Renato Varese. In 2011 the posthumous book Guida alla degustazione del vino: la valutazione edonistica. Concetti propedeutici e formativi esposti in maniera utilizzabile da un ampio ambito di lettori (originally manuscripted by De Rosa during his last days of illness between June and August 1994) was finally published jointly by the Microbiological Institute in Rauscedo and Faenza Editore.

The United States Code of Federal Regulations is the codification (law), or collection of laws specific to a specific to a jurisdiction that represent broad areas subject to federal regulation. Title 42 of the Code of Federal Regulations addresses laws concerning Public Health issues including biosafety which can be found under the citation 42 CFR 73 to 42 CFR 73.21 by accessing the US Code of Federal Regulations (CFR) website. International Biohazard Warning Symbol Title 42 Section 73 of the CFR addresses specific aspects of biosafety including Occupational safety and health, transportation of biohazardous materials and safety plans for laboratories using potential biohazards. While biocontainment, as defined in the Biosafety in Microbiological and Biomedical Laboratories and Primary Containment for Biohazards: Selection, Installation and Use of Biosafety Cabinets manuals available at the Centers for Disease Control and Prevention website much of the design, implementation and monitoring of protocols are left up to state and local authorities.

There are some technical challenges in water reuse, among which are making start-up more economical, questions about water quality standards, long-term effects of pharmaceutical and household chemicals leftover in the water after treatment (constituents of emerging concern), and a lack of infrastructure to carry out water reuse. Although there has been little documentation of adverse effects to humans from water reuse contact or consumption, there remains concern about long-term effects of endocrine disrupters, pharmaceuticals, household chemicals, and personal care products in reused water, including impacts on the natural and beneficial microbiota found on and inside people. Treating water to a degree that would be free of these contaminants is expensive, and, for recycled water that is introduced into a groundwater aquifer, it would include the use of multiple barriers and mediums for removal of the microbiological and chemical contaminants. Furthermore, all wastewater that is added to the groundwater supply must be highly treated just in case it has these potentially dangerous contaminants.

Anellis attended Crane Technical College in Chicago and the University of Illinois at Urbana-Champaign, earning his tuition and living expenses working in a spice factory and as an usher at the Chicago Civic Opera. He received his M.S. degree from the University of Illinois in 1940. At the beginning of 1940, while still working on his doctorate, he was hired by the Illinois Department of Health, in Carbondale, working as a clinical bacteriologist beginning in 1940 and in July 1941 he joined the Northern Regional Research Laboratory of the Bureau of Agriculture and Industrial Chemistry in the Agriculture and Research Administration of the U.S. Department of Agriculture, in Peoria, Illinois, working on the use of microbiologically produced fermentation of farm by-products for production of grain alcohol, including ethanol. In February 1944 Anellis joined the newly created U.S. Army Quartermaster Corps Food and Container Institute in Chicago, and worked on problems of the microbiological safety of foods being shipped overseas to U.S. servicemen.

In the late 20th century, among American winemakers, seemingly healthy fermentation were reported becoming rapidly inundated with high levels of acetic acid that overcame wine yeasts and led to stuck fermentations. While a novel species of Acetobacter or wine spoilage yeast was initially thought to be the culprit, it was eventually discovered to be several species of Lactobacillus, L. kunkeei, L. nagelii, and L. hilgardii, collectively nicknamed "ferocious" Lactobacillus for their aggressive acetic acid production, how quickly they multiply, and their high tolerance to sulfur dioxides and other microbiological controls. Ferments of high-pH wines (greater than 3.5) that spent time cold soaking prior to yeast inoculations and received little to no sulfur dioxide during crushing seem to be at the most risk for "ferocious" Lactobacillus. While infection seems to be vineyard- specific, currently, none of any of the implicated lactobacilli has been reported as being found on the surface of freshly harvested wine grapes.

The quality of water from the public mains is usually quite high and compliant with EU drinking water standards. However, 2011 reports noted poor microbiological quality in some rural private group water schemes and groundwater and challenged the authorities then responsible for drinking water. The city of Galway, supplied with water by the River Corrib, was subject to an outbreak of waterborne cryptosporidiosis in 2007 In 2007, there was an outbreak of waterborne cryptosporidiosis in Galway, which caused illness in over 240 people, and led to the imposition of a boil water notice in Galway for a period of 5 months during the peak tourist season. According to the Environmental Protection Agency (EPA), while "many have taken the quality of drinking water in Ireland for granted in the past, this can no longer be the case".Environmental Protection Agency, 2008, The Provision and Quality of Drinking Water in Ireland – A Report for the Years 2006–2007, p.

Recent reports indicate that locals are slicing the phumdis into sizeable pieces and towing them with canoes to sell to fish culture owners. A scientific study of the water quality parameters of physico-chemical and microbiological characteristics and role of phumdis in the Loktak Lake has been conducted by collecting surface water samples on monthly basis from 15 stations, representing 5 zones; northern, western, eastern, middle and southern. The test results indicated that water quality in the phumdi area was poor in the northern and southern zones of the lake; test results indicated low dissolved oxygen, low pH (normal range for Loktak Lake is 6.3 to 8.2) high CO2 and high Biochemical Oxygen Demand (BOD) but the water quality was good in the open water area. Assessment of the total nitrogen content of the macrophyte species of phumdis indicated that the following were present in descending order: Salvinia natans (1.8%), Zizania latifolia (1.6%), Capillipedium sp.

The Food Safety Act 1990 affords a right for defence analysis, and for referee analysis in case of disputed analytical results, by stipulating that except where to do so would prevent effective analysis the sample must be divided into three parts. The UK Food Standards Agency provides supplementary guidance to the enforcement authorities to assist with the sampling process and associated decisions by sampling officers. There is no set frequency or rate for the sampling of food for law enforcement in the UK. Between the 1930s and 1990s there had been a guideline minimum rate for sampling for chemical analysis (not including samples for microbiological examination) of 2.5 samples per annum per 1000 head of population, however that was an arbitrary figure and more recent thinking suggested that the selection of a frequency for sampling should be based on risk. In this context risk includes all 'consumer protection' issues such as pecuniary disadvantage from substandard or counterfeit products, as well as risk to health.

Tests based on the detection of mycobacterial lipoarabinomannan (LAM) antigen in urine have emerged as point-of-care tests for tuberculosis (TB). LAM antigen is a lipopolysaccharide present in mycobacterial cell walls, which is released from metabolically active or degenerating bacterial cells and appears to be present only in people with active TB disease. Urine-based testing have advantages over sputum-based testing because urine is easy to collect and store, and lacks the infection control risks associated with sputum collection. In 2015, WHO recommended the use of the Alere Determine TB LAM Ag assay for people with HIV and a CD4 count below 100 cells/μL and in those defined as seriously ill according to WHO criteria (respiratory rate >30 breaths per min, body temperature >39 °C, heart rate >120 beats per min, or unable to walk unaided). This recommendation was informed by a Cochrane systematic review and meta-analysis of 12 cross-sectional or cohort studies that showed a relatively low pooled sensitivity of 45% and specificity of 92% against a microbiological reference standard.

Duclaux recommended Roux to Louis Pasteur, who was looking for assistants, and Roux joined Pasteur’s laboratory as a research assistant from 1878 to 1883 at the École Normale Supérieure in Paris. Roux began his research on the microbiological causation of diseases, and in this capacity worked with Pasteur on avian cholera (1879–1880) and anthrax (1879–1890), and was involved in the famous experiment on anthrax vaccination of animals at . In 1883, he presented a doctoral dissertation in medicine titled Des Nouvelles Acquisitions sur la Rage, in which he described his research on rabies with Pasteur since 1881, which led to the development of the first vaccination against this fearsome disease. Roux was now recognized as an expert in the nascent sciences of medical microbiology and immunology. With Pasteur’s other assistants (Edmond Nocard, Louis Thuillier, who died while in Alexandria after contracting the disease, and Straus), Roux traveled in 1883 to Egypt to study a human cholera outbreak there, but they were unable to find the pathogen for the disease, which was later discovered in Alexandria by the German physician Robert Koch (1843–1910).

NCI provided a working model, and a categorical approach organized about specific diseases became the means. Legislation enacted during 1948 made NIH into a plural "Institutes" by adding a National Heart Institute, the National Institute of Dental Research, the National Microbiological Institute (predecessor to the Allergy and Infectious Diseases Institute), and the National Institute of Experimental Biology and Medicine (renamed the National Institute of Arthritis and Metabolic Diseases in 1950), followed by the National Institute of Neurological Diseases and Blindness (1950) and a 500-bed Clinical Center to link bench research with patient care (1953). Lay representation on national advisory councils, construction grants for laboratories, and extramural research grants each contributed to the growing scientific and institutional authority of NIH. He was also a loving great-grandfather. Scheele also inherited projects begun before 1941, whose formal implementation had been delayed by the war, including the transfer of the Interior Department's health bureau for American Indians (1954), the transfer of the Department of Defense's Armed Forces Medical Library (1956, renamed the National Library of Medicine), and new programs to control water pollution (1948), ionizing radiation (1948), and air pollution (1955).
