Biological Abstracts 1969–Present. Further stocks of antiserum can then be produced from the initial donor or from a donor organism that is inoculated with the pathogen and cured by some stock of pre-existing antiserum. Diluted snake venom is often used as an antiserum to give passive immunity to snake venom itself.O'Leary, M.A., K. Maduwage, and G.K. Isbister.

While less accurate than a plaque assay, it is cheaper and quicker (taking just 30 minutes). This assay may be modified to include the addition of an antiserum. By using a standard amount of virus, a standard amount of blood cells, and serially diluting the antiserum, one can identify the concentration of the antiserum (the greatest dilution which inhibits hemagglutination).

The immunized subject is then monitored for antibody response. This often involves the analysis of antiserum samples that contain specific antibodies against the immunizing antigen, and blood lymphocytes from lymphoid organs for examination of T cell- mediated responses. However, some antibodies found in antiserum are cross- reactive. This means that they bind antigens that have no apparent relationship to the immunogen, and are problematic when antiserum is used to detect antigens that bind specifically to these antibodies.

This disease was described in 1919 by Arnold Theiler, a South African veterinary surgeon, after vaccinating horses against African horse sickness using a live virus vaccine and equine antiserum. It was later described in the United States after vaccinating horses for Eastern Equine Encephalitis, again using live virus vaccines and equine-derived antiserum. It has since been reported throughout North America and Europe.

IgM has 10 antigen binding regions per molecule, allowing cross-linking of cells. An antiserum specific for HLA-A3 will then agglutinate HLA-A3 bearing red blood cells if the concentration of IgM in the antiserum is sufficiently high. Alternatively, a second antibody to the invariable (Fc) region of the IgG can be used to cross-link antibodies on different cells, causing agglutination. Complement fixation assay.

The goal is to characterize the concentration of antibodies in the antiserum or other samples containing antibodies. The HI assay is generally performed by creating a dilution series of antiserum across the rows of a 96-well microtiter plate. Each row would usually be a different sample. A standardized amount of virus or bacteria is added to each well, and the mixture is allowed to incubate at room temperature for 30 minutes.

Antiserum is human or nonhuman blood serum containing monoclonal or polyclonal antibodies that is used to spread passive immunity to many diseases via blood donation (plasmaphoresis). For example, convalescent serum, passive antibody transfusion from a previous human survivor, used to be the only known effective treatment for ebola infection with a high success rate of 7 out of 8 patients surviving. Antisera are widely used in diagnostic virology laboratories. The most common use of antiserum in humans is as antitoxin or antivenom to treat envenomation.
|
|
Neutralizing antibodies are used for passive immunisation, and can be used for patients even if they do not have a healthy immune system. In the early 20th century, infected patients were injected with antiserum, which is the blood serum of a previously infected and recovered patient containing polyclonal antibodies against the infectious agent. This showed that antibodies could be used as an effective treatment for viral infections and toxins. Antiserum is a very crude therapy, because antibodies in the plasma are not purified or standardized and the blood plasma could be rejected by the donor.

For many potexviruses these inclusions can be disrupted during the staining procedures. The banded inclusions of ClYMV (Fig.1) however, remain stable and therefore can be diagnostic. Antiserum is available for this virus and, as mentioned above, so is sequence data.

Therefore, a fundamental difference appears to exist in the antigenic composition of the two organisms, which was also demonstrated by cross-absorption in passive cutaneous anaphylaxis test (PCAs). The ability of the given antigen to remove all reactivity from its homologous antiserum while leaving the heterologous antiserum intact indicates the lack of antigen identity. To many scientists, this is enough proof to consider F. novicida and F. tularensis as separate species. Much debate still occurs over how to classify the two organisms, and it is important for scientists to establish a species concept for this organism due to its medical relevance.

When Edward opens a present left for him under the tree, he finds a pair of monogrammed cuff links. When the town's water supply is contaminated, Tracy is seemingly immune to the effects of the pathogen, and decides to undergo tests in order to see if her blood could be used to create an antiserum. Dr. Patrick Drake is able to synthesize a single dose, which Tracy steals to give to Edward. A frail Edward, wise to Tracy's plans, refuses to take the antiserum, and instead requests that she give it to Patrick's daughter Emma Drake.

This condition most commonly occurs after the administration of a horse origin biological agent such as equine-derived antiserum, and usually occurs 4–10 weeks after the event. Diseases that have been vaccinated against using equine-origin antiserum, resulting in subsequent Theiler's disease, include: African horse sickness, Eastern and Western Equine Encephalitis, Bacillus anthracis, tetanus antitoxin, Clostridium perfringens, Clostridium botulinum, Streptococcus equi subspecies equi, Equine influenza, Equine herpesvirus type 1, pregnant mare's serum, and plasma. Although it occurs sporadically, It appears to be spreadable within a premises, and there have been outbreaks occurring on farms involving multiple horses over several months. In the Northern hemisphere it is most common between August to November.

In 1932, she became an instructor and researcher in the Department of Pediatrics at Columbia University, where she spent her entire professional career. In the early 1940s, Alexander began researching Haemophilus influenzae (Hib), at the time an almost invariably fatal disease in infants and young children. From 1941-1945 she served as a consultant to Secretary of War, Henry L. Stimson on the Influenza Commission. She developed an improved antiserum for the disease; by combining antiserum therapy with the use of sulfa drugs, and developing standardized techniques for diagnosis and treatment, she and her associate Grace Leidy helped reduce the mortality rate from Hib from nearly 100 percent to less than 25 percent.

Antivenom, also known as antivenin, venom antiserum, and antivenom immunoglobulin, is a specific treatment for envenomation. It is composed of antibodies and used to treat certain venomous bites and stings. Antivenoms are recommended only if there is significant toxicity or a high risk of toxicity. The specific antivenom needed depends on the species involved.

This unique property became widely used to diagnose pneumococcal infections. Then, using immunological techniques, Neufeld discovered that there were three pneumococcal types. In the presence of type I antiserum type I pneumococci would swell, likewise types II and III in the presence of their specific antisera. Neufeld called this the quellung reaction, after the German word for swelling.

Immunoscreening is a method of biotechnology to detect a polypeptide produced from a cloned gene. The term encompasses several different techniques designed for protein identification, for example Western blotting. Clones are screened for the presence of the gene product (a protein). This strategy requires first that a gene library is implemented in an expression vector, and that antiserum to the protein is available.

When an antiserum is given, the human immune system can mistake the proteins present for harmful antigens. The body produces antibodies, which combine with these proteins to form immune complexes. These complexes precipitate, enter the walls of blood vessels, and activate the complement cascade, initiating an inflammatory response and consuming much of the available complement component 3 (C3). The result is a leukocytoclastic vasculitis.

Her work on this question led to her discovery that a second (later found to be multiple) strains of the organism existed, some that were encapsulated. This research permitted the development of an antiserum and later a vaccine known as Hib against the meningitis caused by one strain (known as the b strain) of H. influenza, which often resulted in blindness and sometimes death in younger children.

|
The direct method is a one-step staining method and involves a labeled antibody (e.g. FITC-conjugated antiserum) reacting directly with the antigen in tissue sections. While this technique utilizes only one antibody and therefore is simple and rapid, the sensitivity is lower due to little signal amplification, in contrast to indirect approaches. However, this strategy is used less frequently than its multi-phase counterpart.

Correct diagnosis of any plant disease requires some expertise. Plants suspected of a viral infection should be sent to a plant disease diagnostic laboratory. One of the specific tests that a plant diagnostic laboratory might perform is an ELISA or serological test where the plant sap is tested against virus specific antiserum made to the capsid protein of the virus.Purcifull, D. E. and T.A. Zitter. 1973.

Doctors at Royaumont also undertook cutting-edge research, focusing on the treatment of gas gangrene. The doctors found X-ray and bacteriology for diagnosis and surgical debridement of affected tissue and antiserum therapy to be especially effective. Doctors at the facility believed the collaboration of different specialties was important in fighting infection and avoiding excess amputations. The hospital had a mobile X-ray car manufactured by Austins and purchased for £300.

Animals are raised for a wide variety of products, principally meat, wool, milk, and eggs, but also including tallow, isinglass and rennet. Animals are also kept for more specialised purposes, such as to produce vaccines and antiserum (containing antibodies) for medical use. Where fodder or other crops are grown alongside animals, manure can serve as a fertiliser, returning minerals and organic matter to the soil in a semi-closed organic system.

There are many commercially available immunologic adjuvants. Selection of specific adjuvants or types varies depending upon whether they are to be used for research and antibody production or in vaccine development. Adjuvants for vaccine use only need to produce protective antibodies and good systemic memory while those for antiserum production need to rapidly induce high titer, high avidity antibodies. No single adjuvant is ideal for all purposes and all have advantages and disadvantages.

Immunofluorescence image of the eukaryotic cytoskeleton. Microtubules as shown in green, are marked by an antibody conjugated to a green fluorescing molecule, FITC. Specific antibodies are produced by injecting an antigen into a mammal, such as a mouse, rat, rabbit, goat, sheep, or horse for large quantities of antibody. Blood isolated from these animals contains polyclonal antibodies—multiple antibodies that bind to the same antigen—in the serum, which can now be called antiserum.

The first uses of bioassay dates back to as early as the late 19th century, when the foundation of bioassays was laid down by a German physician, Paul Ehrlich. He introduced the concept of standardization by the reactions of living matter. His bioassay on diphtheria antitoxin was the first bioassay to receive recognition. His use of bioassay was able to discover that administration of gradually increasing dose of diphtheria in animals stimulated production of antiserum.

This increased research precision helped facilitate and accelerate Stanley's contributions to the advancement of the Tobacco mosaic virus field. Furthermore, she demonstrated that Tobacco mosaic virus in leaf sap could be neutralized, or inactivated, by the antibodies isolated from the antiserum. In conclusion, Beale formed the basis of using immunology and serology to chemically define the Tobacco mosaic virus nature which could be expanded and applied to the virology field in general.

The cDNA sequence of TOAD-64 corresponded to that of rat CRMP-2. In 1996, mouse CRMP-4, often referred to as Ulip for Unc-33 like phosphoprotein, was discovered by Byk and colleagues, using a rabbit polyclonal antiserum which recognized a 64 kDa mouse brain specific phosphoprotein. In the same year, several other studies cloned CRMPs-1-4 in rat and dihydropyrimidinase (DHPase) homologous sequence of CRMPs-1, -2, and -4 in human fetal brain.

In 1904, Emil von Behring founded the Behringwerke in Marburg, Germany, for the purpose of experimental work on disease prevention and for the manufacture of sera and vaccines. In 1913, Behringwerke expanded to produce a gas gangrene antiserum and a cholera vaccine. In 1916, CSL (then Commonwealth Serum Laboratories) was established in Australia with the goal of providing vaccines to the people of Australia and New Zealand. In 1930, CSL released an antivenom for tiger snake bites.

There is a more pronounced difference between the two subspecies with regard to their venom. While Persian horned viper venom exhibits strong hemorrhagic activity typical of most vipers, the venom of P. fieldi is unusual in that contains several fractions that show marked neurotoxic activity. No antivenin is available for bites from either subspecies. It is reported that a polyvalent antiserum does offer some protection from the hemotoxins, but none against the neurotoxic effects of P. fieldi venom.

Serum sickness in humans is a reaction to proteins in antiserum derived from a non-human animal source, occurring 5–10 days after exposure. It is a type of hypersensitivity, specifically immune complex hypersensitivity (type III). The term serum sickness–like reaction (SSLR) is occasionally used to refer to similar illnesses that arise from the introduction of certain non-protein substances, such as penicillin. It was first characterized by Clemens von Pirquet and Béla Schick in 1906.

This type of cell fusion is widely used for the production of somatic cell hybrids and for nuclear transfer in mammalian cloning. Sendai virus induced cell fusion occurs in four different temperature stages. During the first stage, which lasts no longer than 10 minutes, viral adsorption takes place and the adsorbed virus can be inhibited by viral antibodies. The second stage, which is 20 minutes, is pH dependent and an addition of viral antiserum can still inhibit ultimate fusion.

Jadwiga was in charge of infirmary and prevented the outbreak of typhoid fever by begging the SS for antiserum. The number of women she saved can only be guessed. On a daily basis, she would treat patients coming in with great oversight from SS doctors, holding her accountable of any person that was not truly sick. In her biography, she often recounts that the ethical lines in medicine were often blurred due to the lack of supplies and brutality of the camps.

In World War I, injection of tetanus antiserum from horses was widely used as a prophylaxis against tetanus in wounded soldiers, leading to a dramatic decrease in tetanus cases over the course of the war. The modern method of inactivating tetanus toxin with formaldehyde was developed by Gaston Ramon in the 1920s; this led to the development of the tetanus toxoid vaccine by P. Descombey in 1924, which was widely used to prevent tetanus induced by battle wounds during World War II.

Rosalia's blood seeped into the surrounding Asclepias and turned them blue, with the monarch butterflies feeding on them becoming the virus's vector due to shedding their scales during their migration. While Rosalia's blood is unusable, an antiserum is developed using the blue Asclepias. They return to Resurgam and the doctors begin bringing the epidemic under control. Naomi then collapses; she is infected with the virus, which has merged with her own condition to form a mutant strain dubbed "Twisted Rosalia".

He continued this work at the College of Physicians and Surgeons of Columbia University, where he became faculty in 1921. Dochez's work was the first to demonstrate that scarlet fever was directly related to streptococcal pharyngitis. He also demonstrated that most strains of streptococci from scarlet fever patients belonged to a single specific type of bacteria. Dochez developed an antiserum capable of treating scarlet fever, but was forced to terminate production, and all further research on scarlet fever, due to patent infringement.

The immune system then recognizes foreign agents bound to antibodies and triggers a more robust immune response. The use of antiserum is particularly effective against pathogens which are capable of evading the immune system in their unstimulated state but are not robust enough to evade the stimulated immune system. The existence of antibodies to the agent depends on an initial survivor whose immune system, by chance, discovered a counteragent to the pathogen or a host species which carries the pathogen but does not suffer from its effects.

In 1906, antiserum was produced in horses; this was developed further by the American scientist Simon Flexner and markedly decreased mortality from meningococcal disease. In 1944, penicillin was first reported to be effective in meningitis. reproduced in The introduction in the late 20th century of Haemophilus vaccines led to a marked fall in cases of meningitis associated with this pathogen, and in 2002, evidence emerged that treatment with steroids could improve the prognosis of bacterial meningitis. World Meningitis Day is observed on 24 April each year.

Symptoms of PepMoV on pepper include dark green vein banding, mottle/mosaic, puckered or crinkled leaves, and misshapen fruit. Plants infected early in the growing season can be stunted and the virus can decrease yield significantly. (See pictures of symptoms) Surveys have shown that PepMoV can often occur in mixed infections with TEV and/or PVY so a technique such as ELISA must be used to differentiate these three virus in pepper. Antiserum is available for all three potyviruses, as are primers for PCR tests and sequencing.

The lung edema induced by TsTX is blocked by phenobarbital. Rabbit anti-TsNTxP antibodies displayed cross-reactivity with the scorpion toxins and showed in vitro neutralizing capacity. Thus, this protein emerges as a strong candidate for the production of antiserum to be used in the treatment of scorpion stings. The nontoxic recombinant protein can induce a level of circulating antibodies sufficient to neutralize the toxic effects of Tityus toxins and is a good candidate for use in the production of a new generation of neutralizing polyclonal antibodies for clinical use.

Single radial immunodiffusion assay (SRID), also known as the Mancini method, is a protein assay that detects the amount of specific viral antigen by immunodiffusion in a semi-solid medium (e.g. agar). The medium contains antiserum specific to the antigen of interest and the antigen is placed in the center of the disc. As the antigen diffuses into the medium it creates a precipitate ring that grows until equilibrium is reached. Assay time can range from 10 hours to days depending on equilibration time of the antigen and antibody.

C1 protein is also known as the viral replication protein, which makes it essential for virus replication. C2, C3, and C4 proteins have been associated to function as a post-transcriptional gene silencing suppressor, a virus accumulation enhancer, and a symptom induction determinant, respectively. In the insect vector, a study found that TYLCV had a high binding affinity to a GroEL homolog, a molecular chaperon essential for protein folding. Therefore, after feeding B. tabaci with a diet containing antiserum against GroEL, they found TYLCV transmission to be reduced.

In the Behring facilities, the horses were viewed as life savers; therefore, they were well treated. A few of the individual horses used for serum production were named, and celebrated for their service to medicine, both human and non-human. At the end of the 19th century, every second child in Germany was infected with diphtheria, the most frequent cause of death in children up to 15 years. In 1891 Emil Behring saved the life of a young girl with diphtheria by injecting antiserum for the first time in history.

Even though they tried to empower the immune system of the horses during this immunization with painstaking care, most of the horses suffered appetite loss, fever, and in worse cases shock and dyspnea. The highest immunization risk for horses was the production of antiserum for snake venom. The horse was immunized with all types of snake poison at the same time because it was not always possible to know by which snake species a person had been bitten. Therefore, the serum had to immunize the subject against the venom of every snake species.

In India, the natural hosts of ICMV are Manihot esculenta and Manihot carthaginensis subsp. glaziovii. Additionally, Jatropha curcas shows mosaic symptoms similar to cassava infected by ICMV; affected leaves have been shown to react in ELISA bioassay trials to African cassava mosaic virus antiserum, but follow up with a DNA B probe has provided negative results. This mosaic disease may be a new strain of ICMV affecting J. curcas, a plant with a potential as a biofuel crop, and it may become necessary to develop virus- resistant clones.

Later, Alexander and Leidy studied the effect of antibiotics on Hib, finding streptomycin to be highly effective. The combined use of the antiserum, sulfa drugs, and antibiotics significantly lowered the mortality rate from Hib. In the course of her research on antibiotics, Alexander noted and reported the appearance of antibiotic- resistant strains of Hib. She concluded, correctly, that this was caused by random genetic mutations in DNA which were positively selected through evolution; she and Leidy demonstrated the occurrence of transformation in the Hib bacillus, leading to resistance.

Biochemical studies showed that the antiserum recognized a chondroitin sulfate proteoglycan with a core glycoprotein of 300 kDa, and the antigen was named NG2 (nerve/glial antigen 2). NG2 was found to be expressed on A2B5+ oligodendrocyte precursor cells isolated from the perinatal rat CNS tissues and on process-bearing cells in the CNS in vivo. Comparison of NG2 and Pdgfra expression revealed that NG2 and Pdgfra are expressed on the same population of cells in the CNS. These cells represent 2-9% of all the cells and remain proliferative in the mature CNS.

Ehrlich popularized the concept of a magic bullet. He also made a decisive contribution to the development of an antiserum to combat diphtheria and conceived a method for standardizing therapeutic serums. In 1908, he received the Nobel Prize in Physiology or Medicine for his contributions to immunology.The Nobel Prize in Physiology or Medicine 1908, Paul Erlich - Biography He was the founder and first director of what is now known as the Paul Ehrlich Institute, a German research institution and medical regulatory body that is the nation's federal institute for vaccines and biomedicines.

The serum of convalescent patients successfully recovering (or already recovered) from an infectious disease can be used as a biopharmaceutical in the treatment of other people with that disease, because the antibodies generated by the successful recovery are potent fighters of the pathogen. Such convalescent serum (antiserum) is a form of immunotherapy. Serum is also used in protein electrophoresis, due to the lack of fibrinogen which can cause false results. Fetal bovine serum (FBS) is rich in growth factors and is frequently added to growth media used for eukaryotic cell culture.

Tragically, he does not reunite with his sister, who also takes part in the escape group but is killed moments before the group reaches the border of the city. George helps Four and his group to infiltrate Chicago so he and Christina can inject the memory antiserum for their and Uriah's families. In the epilogue, Four mentions that George has been working as a police tutor after the war, although he himself does not physically appear nor join the zipline play in commemoration of the Choosing Day. George does not appear in the film series.

The detection of the virus through the DNA probe also helps identify a contaminated environment the bird has recently been exposed to. An indirect immunoperoxidase method is another chemically sensitive and specific testing that laboratories have used to arrive at a reliable result in making a histopathological diagnosis of Pacheco’s disease. This test does not require highly complex devices or sources. It detects the presence of the avian alpha- herpesvirus, which is the causative agent, through an antiserum obtained in SPF chickens as well as another serum obtained from rabbit anti-chicken IgG that is conjugated with horseradish peroxidase.

In 1901 he married Henrietta Dixon and transferred to the Lister Institute of Preventive Medicine where the work on the medium was completed with suggestions from the Liverpool laboratory for the inclusion of neutral red and crystal violet. In 1906 he became responsible for the Serum Department and was heavily involved in production of antiserum for both diphtheria and tetanus, the latter being especially important for treatment of battlefield injuries during the First World War. He succeeded, as requested, in making the department profitable although some questioned his authoritarian management style.Chick, H., Hume, M., & Macfarlane, M. (1971).

This again demonstrates his tendency to quantify the life sciences. Influenced by the mayor of Frankfurt am Main, Franz Adickes, who endeavored to establish science institutions in Frankfurt in preparation of the founding of a university, Ehrlich's institute moved to Frankfurt In 1899 and was renamed the Royal Prussian Institute of Experimental Therapy (Königlich Preußisches Institut für Experimentelle Therapie). The German quality-control methodology was copied by government serum institutes all over the world, and they also obtained the standard serum from Frankfurt. After diphtheria antiserum, tetanus serum and various bactericide serums for use in veterinary medicine were developed in rapid sequence.

As of 2012, IMC has not become widely used in cultured cell toxicology even though it has been used periodically and successfully since the 1980s. IMC is advantageous in toxicology when it is desirable to observe cultured cell metabolism in real time and to quantify the rate of metabolic decline as a function of the concentration of a possibly toxic agent. One of the earliest reports (Ankerst et al. 1986) of IMC use in toxicology was a study of antibody-dependent cellular toxicity (ADCC) against human melanoma cells of various combinations of antiserum, monoclonal antibodies and also peripheral blood lymphocytes as effector cells.

He purified human C-reactive protein through crystallization, produced a highly specific antiserum, and, using this much simpler and more sensitive test, found that C-reactive protein levels responded more rapidly and reliably than other inflammatory markers and could serve as the most accurate indicator of rheumatic inflammatory activity. Measuring C-reactive protein levels to detect inflammation is routine now in medical practice. In his later years, McCarty increasingly served as a statesman of the biomedical sciences. He served for 14 years as the physician-in-chief of the Rockefeller University Hospital, and as a trusted adviser and the vice president of the Rockefeller University.

Emil Behring had worked at the Berlin Institute of Infectious Diseases until 1893 on developing an antiserum for treating diphtheria and tetanus but with inconsistent results. Koch suggested that Behring and Ehrlich cooperate on the project. This joint work was successful to the extent that Ehrlich was quickly able to increase the level of immunity of the laboratory animals based on his experience with mice. Clinical tests with diphtheria serum early in 1894 were successful and in August the chemical company Hoechst started to market Behring's “Diphtheria Remedy synthesized by Behring- Ehrlich.” The two discoverers had originally agreed to share any profits after the Hoechst share had been subtracted.

She demonstrated infected leaf sap injected into rabbits could produce polyclonal antibodies in rabbit antiserum that were not found in the control (non-infected leaf sap injections). The antibodies were specific to Tobacco mosaic virus, thus identifying and characterizing the virus as a pathogenic agent in tobacco mosaic disease. The specificity of the antibody for Tobacco mosaic virus, being unreactive with other viruses, proved to be a useful tool with which to diagnose a Tobacco mosaic virus infection. It also allowed for the isolation and characterization of unique strains of Tobacco mosaic virus, making it possible for her collaborator, Wendell M. Stanley, to work with a single pure strain.

The results of antibody-dependent cellular cytotoxicity assay on guineas-pig Kurloff cells strongly indicate an immunological role of the cells as the natural killer cell. The data also suggest that the Kurloff cell is probably the predominant cytotoxic line in guinea pig lymphocyte composition, and different level of killer cell activities depends mostly on varying degrees of Kurloff cell contamination. The Kurloff cells were suggested to have an impact on the immunological status of the guinea-pig placenta. The fate of cells in pregnant guineas pig has been studied by immunofluorescent methods, including an antiserum against the isolated mucoprotein of the inclusion body.

Prolonged periods of wetness and/or poorly drained soils, followed by warm, sunny days and cool nights constitute the optimal conditions for bacterial wilt. Thus, transitions between spring and summer, and summer and autumn are usually accompanied by increases in bacterial wilt of turf grass as these seasonal changes, especially in the early fall, bring sustained rainfalls and longer, cooler nights. Bacterial wilt of turf grass has been reported in several regions of Illinois, as well as other Midwestern states such as Michigan, Ohio, and Wisconsin. Antiserum produced from an isolate of this pathogen in Illinois was found to have reacted to another such isolate from Europe, suggesting that the pathogen was brought over to North America from Europe.

The first therapies for the treatment of diphtheria and tetanus came into use in the mid-1890s and had a major impact on the development of the history of medicine. Emil Behring (1854–1917) had pioneered the technique, using guinea pigs to produce serum. Based on his observation that people who survived infection with the diphtheria bacterium never became infected again, he discovered that the body continually produces an antitoxin, which prevents survivors of infections from being infected again with the same agent. It was necessary for Behring to immunize larger animals in order to produce enough serum to protect humans, because the amount of antiserum produced by guinea pigs was too little to be practical.

At the initiative of Friedrich Althoff,an influential staff member in the Prussian Ministry of Religious, Educational and Medical Affairs (Preußisches Ministerium der geistlichen, Unterrichts- und Medizinalangelegenheiten) an Institute of Serum Research and Testing (Institut für Serumforschung und Serumprüfung) was established in 1896 in Berlin- Steglitz, with Paul Ehrlich as director (which required him to cancel all his contracts with Hoechst). In this function and as honorary professor at Berliner University he had annual earnings of 6,000 marks, approximately the salary of a university professor. In addition to a testing department the institute also had a research department. In order to determine the effectiveness of diphtheria antiserum, a stable concentration of diphtheria toxin was required.

In 1887, he observed that leukocytes isolated from the blood of various animals were attracted towards certain bacteria. The first studies of leukocyte killing in the presence of specific antiserum were performed by Joseph Denys and Joseph Leclef, followed by Leon Marchand and Mennes between 1895 and 1898. Almoth E. Wright was the first to quantify this phenomenon and strongly advocated its potential therapeutic importance. The so-called resolution of the humoralist and cellularist positions by showing their respective roles in the setting of enhanced killing in the presence of opsonins was popularized by Wright after 1903, although Metchnikoff acknowledged the stimulatory capacity of immunosentisitized serum on phagotic function in the case of acquired immunity.

Due to the simple purification of this enzyme (5-30 fold purification is sufficient to reach homogeneity), its biological and biochemical analysis have been very thoroughly studied. In addition to the study of many isoforms within a given organism, there has been study dedicated to the understanding of HNL localization, the physical structure of the enzyme and its active site, and the mechanisms by which it is able to mediate this important set of reactions. Upon the purification of Black Cherry HNL, research from Wu and Poulton raised antiserum to these specific HNL, which were then applied (with colloidal gold particles in tow) to Black Cherry cotyledon and endosperm. Here it was found that HNL overwhelmingly localizes to the cell walls of these developing plants.

Dutta did extensive researches on cholera and pioneered the use of infant rabbits for developing a laboratory model for the studies which is reported to have promoted cholera studies in countries where the disease was not prevalent. In 1959, he identified the toxin generated by Vibrio cholerae which causes diarrhoea during animal testing and he used the classical biotype, Inaba serotype, V. cholerae strain 569B for the first time, which is being followed today. He also developed a methodology for the evaluation of vaccines and antiserum and was known to have proposed therapeutic protocols for treating cholera. He documented his researches by way of several medical papers published in peer-reviewed journals and his work has been cited by a number of authors and researchers.

Present vaccination strategies for SIV control and prevention in swine farms typically include the use of one of several bivalent SIV vaccines commercially available in the United States. Of the 97 recent H3N2 isolates examined, only 41 isolates had strong serologic cross-reactions with antiserum to three commercial SIV vaccines. Since the protective ability of influenza vaccines depends primarily on the closeness of the match between the vaccine virus and the epidemic virus, the presence of nonreactive H3N2 SIV variants suggests current commercial vaccines might not effectively protect pigs from infection with a majority of H3N2 viruses. The United States Department of Agriculture researchers say while pig vaccination keeps pigs from getting sick, it does not block infection or shedding of the virus.

The researchers found that antiserum to Pseudomonas fluorescens or Erwinia herbicola from hosts which have survived infections by the corresponding pathogens is capable of reducing wilt symptoms in turf grass caused by Xanthomonas campestris pv. graminis. The researchers did note, however, that while it is important to ensure the presence of a higher number of competing bacterial cells in order to reduce symptoms, one should take care to avoid over-infecting the host with a new bacterial pathogen. Further gains towards host resistance were made in 2001 when researchers found that inoculation of meadow fescue during breeding with a single aggressive strain of the bacterial wilt pathogen greatly increased resistance in offspring, thereby demonstrating the potential of selective breeding to reduce bacterial wilt pathogenesis on turf and rye grasses.

His success at producing a vaccine to combat an outbreak of smallpox among the miners of the Witwatersrand brought him an appointment as state veterinarian for the Zuid-Afrikaansche Republiek, in which capacity he served during the Anglo-Boer War of 1899-1902. During this period his research team developed a vaccine against rinderpest, a malignant and contagious disease of cattle. His tremendous energy, pioneering spirit and professional integrity brought him international recognition. He described in 1919 what is now known as Theiler's disease (acute serum hepatitis, postvaccination hepatitis or idiopathic acute hepatic disease) - one of the most common causes of acute hepatitis in horses - when he observed the symptoms of liver disease in animals vaccinated against African horse sickness with a combination of live virus and equine antiserum.

Samples (vaginal, rectal, or vaginorectal swabs) should be inoculated into a selective enrichment broth, (Todd Hewitt broth with selective antibiotics, enrichment culture). This involves growing the samples in an enriched medium to improve the viability of the GBS and simultaneously impairing the growth of other naturally occurring bacteria. After incubation (18–24 hours, 35-37 °C), the enrichment broth is subcultured to blood agar plates and GBS-like colonies are identified by the CAMP test or using latex agglutination with GBS antiserum. In the UK, this is the method described by the Public Health England's UK Standards for Microbiology Investigations After incubation, the enrichment broth can also be subcultured to granada medium agar where GBS grows as pinkish-red colonies or to chromogenic agars, where GBS grows as coloured colonies.

Production of antiserum at the Institut Pasteur in Paris Not long after the institute's inauguration, Roux, now less occupied in the fight against rabies, resumed in a new lab and with the help of a new colleague, Yersin, his experiments on diphtheria. This disease used to kill thousands of children every year: an associated condition was commonly called croup, which created fake membranes in the small patients' throats, therefore killing them by suffocation. It was deservedly called “Horrible monster, sparrowhawk of the shadows” by Victor Hugo in his Art of being a grandfather. The painter Albert Gustaf Aristides Edelfelt made a famous painting portraying Pasteur in his laboratory while he was trying to cure this illness, which was fought at the times through procedures that were just as cruel as the illness itself.

Passive immunity is the transfer of active humoral immunity of ready-made antibodies. Passive immunity can occur naturally, when maternal antibodies are transferred to the fetus through the placenta, and it can also be induced artificially, when high levels of antibodies specific to a pathogen or toxin (obtained from humans, horses, or other animals) are transferred to non-immune persons through blood products that contain antibodies, such as in immunoglobulin therapy or antiserum therapy. Passive immunization is used when there is a high risk of infection and insufficient time for the body to develop its own immune response, or to reduce the symptoms of ongoing or immunosuppressive diseases.Microbiology and Immunology On-Line Textbook: USC School of Medicine Passive immunization can be provided when people cannot synthesize antibodies, and when they have been exposed to a disease that they do not have immunity against.

In a separate series of studies, cells from perinatal rat optic nerves that expressed the A2B5 ganglioside were shown to differentiate into oligodendrocytes in culture. Subsequently, A2B5+ cells from other CNS regions and from adult CNS were also shown to generate oligodendrocytes. Based on the observation that these cells require PDGF for their proliferation and expansion, the expression of the alpha receptor for platelet-derived growth factor (Pdgfra) was used to search for the in vivo correlates of the A2B5+ cells, which led to the discovery of a unique population of Pdgfra+ cells in the CNS whose appearance and distribution were consistent with those of developing oligodendrocytes. Independently, Stallcup and colleagues generated an antiserum that recognized a group of rat brain tumor cell lines, which exhibited properties that were intermediate between those of typical neurons and glial cells.

The pneumococcal quellung reaction was first described in 1902 by the scientist Fred Neufeld, and applied only to Streptococcus pneumoniae, both as microscopic capsular swelling and macroscopic agglutination (clumping visible with the naked eye). It was initially an intellectual curiosity more than anything else, and could distinguish only the three pneumococcal serotypes known at that time. However, it acquired an important practical use with the advent of serum therapy to treat certain types of pneumococcal pneumonia in the 1920s because selection of the proper antiserum to treat an individual patient required correct identification of the infecting pneumococcal serotype, and the quellung reaction was the only method available to do this. Dr. Albert Sabin made modifications to Neufeld's technique so that it could be done more rapidly, and other scientists expanded the technique to identify 29 additional serotypes. Application of Neufeld’s discoveries to other important areas of research came when Fred Griffith showed that pneumococci could transfer information to transform one serotype into another.
