This year, scientists have performed 18 necropsies — examinations of corpses — on dead minke whales.
|
|
Necropsies are being performed to determine why the whales ended up on the beach.
|
|
Necropsies have confirmed the cause of seven of the previous eight whale deaths this year.
|
|
Necropsies on the animals are being conducted, but it could be months before the results are in.
|
|
"Necropsies also showed that those birds had high levels of heavy metals in their kidneys," the Billings Gazette reported.
|
|
The ASPCA said it will conduct necropsies to find how the cats died, but it will take several days.
|
|
This summer Mr. Okoniewski has already examined more than 20 dead birds, while twice that many are awaiting necropsies.
|
|
They've been helping conduct field necropsies, Conn said, as they have been unable to move most of the horses.
|
|
The researchers couldn't design an experiment, and instead just began taking data, observing the dying animals and performing necropsies afterwards.
|
|
The veterinarian Michael Moore of the Woods Hole Oceanographic Institution has conducted necropsies on right whales for more than two decades.
|
|
Necropsies (animal autopsies) are being performed on the carcasses to try to determine why the whales ended up on the beach.
|
|
The center does necropsies on wild animals sent to it by agencies like Fish and Wildlife and keeps track of what it finds.
|
|
The study examined data from two sets of Australian sea turtles: necropsies of 246 animals and 706 records from a national strandings database.
|
|
"It is critical for scientists to conduct in-depth necropsies to better understand why animals are dying," the center said in a news release.
|
|
The NPS says that necropsies of the ducklings revealed the cause: A parasite that develops and grows in snails that live in the pool.
|
|
The dead whales were taken by the Georgia Department of Natural Resources for necropsies "to assess their prior health and cause of death," the agency said.
|
|
The researchers carried out their research by conducting necropsies -- animal autopsies -- on turtles that had died either by stranding or by being accidentally caught by fishermen.
|
|
It's still unclear what factors, including a prolonged period of heavy rain, led to this series of catastrophic breakdowns; necropsies and an investigation might provide answers.
|
|
When Peterson later combed through old pathology reports for 7,21950 feline necropsies, he found that the thyroid abnormalities he was seeing were rare until the late 21956s.
|
|
NOAA Fisheries is working with its partners in the Alaska Marine Mammal Stranding Network to photograph and perform necropsies on the animals, NOAA said in a news release.
|
|
The zoo is conducting necropsies and an investigation of the building to learn more - and what they can do to make sure it doesn't happen to the 19 creatures that remain.
|
|
The researchers try to move the whales to places where they can conduct necropsies and then leave the carcass to decay naturally, a process that can take a year or more.
|
|
While necropsies indicate there is "pre-existing pathology" associated with about 90% of the fatal injuries, doctors are working on ways to detect those conditions before it's too late, the board said.
|
|
Melissa Miller, a Department of Fish and Wildlife veterinarian who has overseen hundreds of otter necropsies, said more research was needed to fully understand how domoic acid was harming the otter population.
|
|
"I'd like to see the necropsies come out," she said, referring to the equine autopsy reports that are now in the hands of investigators for the Los Angeles County District Attorney's office.
|
|
Each year Mr. Okoniewski, a wildlife pathologist with the New York State Department of Conservation, performs necropsies on small numbers of seabird specimens that wash up dead along the coastal parts of the state.
|
|
The outlet also said that both a grizzly bear and black bear found in the area were killed on Friday, and authorities will conduct necropsies to determine if either animal were involved in the fatal attack.
|
|
The cause of death is unknown, but vets and scientists will perform necropsies — whale autopsies — on the retrieved bodies to determine whether ship strikes, entanglement in fishing gear, or toxic algal blooms could be to blame.
|
|
Necropsies of stranded whales also suggest that sinus and ear parasites or injuries from seismic activity, such as US Navy sonar tests or deepsea oil exploration, can inhibit a whale's senses and ability to navigate its surroundings.
|
|
A man found the animal lying at the water's edge in April and called the Institute for Marine Mammal Studies, which responds to dolphin strandings and conducts necropsies, or animal autopsies, said Moby Solangi, the organization's executive director.
|
|
When California racehorses die, they're sent to UC Davis for necropsies; the results of the 30 horses who died at Santa Anita have not yet been released because of an investigation by the Los Angeles District Attorney's office.
|
|
Ms. Thomson said wildlife officials would explore the possibility that the birds had died from a poison, but added that nothing would be known until necropsies and X-rays were performed at a United States Fish and Wildlife Services forensics laboratory in Oregon, where the carcasses were shipped on Monday night.
|
|
Officials I spoke with via email weren't sure of the specific name of the parasite—I've asked the researchers at the USGS National Wildlife Health Center, who performed the necropsies, and will update when we hear an answer—but as parasites that harm duck populations go, a good bet would be on the same invasive species that lives in faucet snails, which damaged duck populations in the Upper Mississippi in 2008 and 2016.

Outdoor workers (including biological fieldworkers, construction workers, farmers, landscapers, and painters), healthcare personnel, and laboratory personnel who perform necropsies on animals are at risk of contracting WNV. In 2012, the US experienced one of its worst epidemics in which 286 people died, with the state of Texas being hard hit by this virus.

Sambon only gave partial description using a male worm. In 1908, a Brazilian physician Manuel Augusto Pirajá da Silva gave a complete description of male and female worms, including the lateral-spined eggs. Pirajá da Silva obtained specimens from three necropsies and eggs from 20 stool examinations in Bahia. He gave the name S. americanum.

World Health Organization, Enivironmental Health Criteria 235, Dermal Absorption, 2006. In some test protocols many animals may be tested and necropsies may occur at set intervals after exposure. Biomonitoring, such as taking urine samples at intervals, from workers exposed to chemicals may provide some information but it is difficult to distinguish dermal from inhalation exposure using this method.

Chamois are antelope-like animals that are found naturally in the mountains of Europe. The animals at the zoo died over a 7-year period. After completing necropsies, it was determined that the organisms were infected with a parasitic protozoan of the genus Eimeria. This species had produced megaloschizonts in the intrahepatic bile ducts and portal veins.

Volunteers attempt to keep body temperatures of beached pilot whales from rising at Farewell Spit, New Zealand. There is evidence that active sonar leads to beaching. On some occasions cetaceans have stranded shortly after military sonar was active in the area, suggesting a link. Theories describing how sonar may cause whale deaths have also been advanced after necropsies found internal injuries in stranded cetaceans.

The viral particles can be detected in fecal matter within 2 days and peak virus shedding occurs 4–5 days after infection. The virus can be found in the kidney, jejunum, spleen, liver and bursa of infected birds. Symptoms of this disease include diarrhea and weight loss. Necropsies show swollen and discolored kidneys and there is evidence of death of the epithelial cells and lymphocytic interstital nephritis.

Chronic wasting disease was first discovered by American wildlife veterinarian Beth S. Williams. Williams performed necropsies on deer and elk that had died of an unknown syndrome. She recognized that the brain lesions in these animals were consistent with transmissible spongiform encephalopathy (TSE). In 1978, she and neuropathologist Stuart Young cowrote the first scientific paper that named the disease and described it as a TSE.

Eustrongylidosis can be diagnosed before or after death by observing behavior and clinical signs, and performing fecal flotations and necropsies. Methods to control it include preventing eutrophication and providing hosts with uninfected food sources in aquaculture farms. Parasites are known to be indicators of environmental health and stability, so should be studied further to better understand the parasite's lifecycle and how it affects predator-prey interactions and improve conservation efforts.

After more than 100 live and approximately 150 dead Chihuahuas and Chihuahua-mixes were removed from Kenneth Lang Jr's home in 2009, the Animal Legal Defense Fund provided a grant of $3,500 to allow the Dearborn Police Department to conduct necropsies on 10 of the Chihuahuas whose bodies were removed from freezers on 56-year-old Lang's property. Kenneth Lang Jr. pleaded guilty to animal cruelty in January 2010.

In 2006, Brucella was found in a dead Māui dolphin and DOC says this bacterial infection could have serious ramifications for the small Māui population. Brucellosis is a disease of terrestrial mammals that can cause late pregnancy abortion, which has been found in a range of cetacean species elsewhere, and has been determined from necropsies to have been the primary cause of death of both Hector's and Māui dolphins.

Dosages of 2.8, 5.6, and 9.1 g/kg were used, with the highest dose administered being considerably more than any house cat could consume. The cats showed none of the symptoms found in past epidemiological studies and appeared normal. Necropsies showed nothing that would suggest toxicity. The past epidemiological studies have been suggested to be wrong, since sick cats may be inclined to eat plants to alleviate their illnesses.

The painful and inevitable death that follows usually prompts veterinarians and owners to euthanize foals suspected of having lethal white syndrome. Death is caused by an underdeveloped part of the digestive system. The large intestine of the horse is a complex system where most digestion takes place, and comprises the cecum, the colon, and the rectum. Necropsies on LWS foals reveal a pale, underdeveloped colon and intestinal obstruction (impaction).

As more dead chimpanzees were discovered, many tested positive for Ebola using molecular techniques. The source of the virus was believed to be the meat of infected western red colobus monkeys (Procolobus badius) upon which the chimpanzees preyed. One of the scientists performing the necropsies on the infected chimpanzees contracted Ebola. She developed symptoms similar to those of dengue fever approximately a week after the necropsy, and was transported to Switzerland for treatment.

Clinical signs of infected seals included debilitation, muscle spasms, ocular and nasal exudation, and sneezing. Necropsies performed in June 2000 on eight Azerbaijan seals revealed microscopic lesions, including bronchointerstitial pneumonia, encephalitis, pancreatitis, and lymphocytic depletion in lymphoid tissues. Similar lesions were also discovered on four seals from Kazakhstan. Morbillivirus antigen was also detected in multiple tissues, including lung, lymph nodes, spleen, brain pancreas, liver, and epithelial tissue of the reproductive, urinary, and gastrointestinal tracts.

VanBlaricom, p. 62 In California, adults of breeding age have experienced high levels of mortality in recent years. Although the bodies of dead sea otters often sink at sea, necropsies of beached carcasses provide some insights into the causes of mortality. A study of 105 sea otters that had washed ashore between 1998 and 2001 determined the major causes of death to be protozoal encephalitis, acanthocephalan parasite infection, shark attack, and cardiac disease.

It is predicted that by 2050, 99% of seabirds will have consumed such materials. Scientists studying the stomach contents of Laysan Albatross chicks report a 40% mortality rate before fledging. When the stomach contents were analyzed following necropsies, they were found to contain plastic waste. Not only do plastic pellets used in manufacturing worldwide absorb toxic chemicals such as DDT and PCBs from the water, but they can even leach chemicals such as biphenyl.

From 1906 to 1946 Turnbull was the director of London Hospital's Institute of Pathology. At London University he became in 1915 reader in morbid anatomy, in 1915 professor, and in 1947 professor emeritus. In 1924 he became M.R.C.P. At London Hospital's Institute of Pathology he established an outstanding department with a high standard of accuracy in biopsies and necropsies. In 1916 Turnbull married Catherine Nairne Arnold-Baker, the younger daughter of Frederick Arnold-Baker.

Some little penguins are drowned when amateur fishermen set gill nets near penguin colonies. Discarded fishing line can also present an entanglement risk and contact can result in physical injury, reduced mobility or drowning. In 2014, a group of 25 dead little penguins was found on Altona Beach in Victoria. Necropsies concluded that the animals had died after becoming entangled in net fishing equipment, prompting community calls for a ban on net fishing in Port Phillip Bay.

According to German conservationist Werner Smolnik, the toads expanded to three and a half times their normal size before blowing up, and were noted to live a short time after exploding. Berlin veterinarian Franz Mutschmann collected toad corpses and performed necropsies. He theorised that the phenomenon was linked to a recent influx of predatory crows to the area. He stated that the cause was a mixture of crow attacks and the natural puff up defense of the toads.

The similar species Chiropsoides quadrigatus may be the same species as C. buitendijki; this has been debated since some of the “distinct” features of C. quadrigatus too closely resemble those same “distinct” features found in C. buitendijki. Distinctive features are what identify a species as their own unique taxonomic group. If the features that distinguish each of these species are the same, then it is possible they are in fact one species. More sampling and necropsies are needed to make a clearer distinction.

In 1942 it famously carried out tests of an anthrax bio-weapon developed at Porton Down at Gruinard Island. He also assisted with the anthrax strain tests on Gruinard Island, performing necropsies on the bodies of anthrax-exposed sheep, to determine if they had died as a direct result of anthrax poisoning. This work produced the world's first working anthrax bomb in the summer of 1942.Guillemin, Jeanne (2005), Biological Weapons: From the Invention of State-Sponsored Programs to Contemporary Bioterrorism, ( Internet Archive), Columbia University Press, pp.

The U.S. Navy had scheduled 14 training exercises through January 2009 off the coast of Southern California involving the use of “mid-frequency active sonar” to detect enemy submarines. Environmentalists argued that the sonar's high decibel levels may have a deafening effect on whales. They said studies conducted around the world have shown the piercing underwater sounds cause whales to flee in panic or to dive too deeply. Whales have been found beached in Greece, the Canary Islands, and in the Bahamas after sonar was used in the area, and necropsies showed signs of internal bleeding near the ears.

Despite its status as a Level‑4 organism and its apparent pathogenicity in monkeys, RESTV did not cause disease in exposed human laboratory workers. ; Taï Forest ebolavirus (TAFV): Formerly known as "Côte d'Ivoire ebolavirus", it was first discovered among chimpanzees from the Tai Forest in Côte d'Ivoire, Africa, in 1994. Necropsies showed blood within the heart to be brown; no obvious marks were seen on the organs; and one necropsy displayed lungs filled with blood. Studies of tissues taken from the chimpanzees showed results similar to human cases during the 1976 Ebola outbreaks in Zaire and Sudan.

The birds were sent to laboratories in Georgia and Wisconsin for necropsies and to determine the cause of death. On January 5, the Arkansas Game and Fish Commission confirmed that the incident was caused by a resident setting off professional-grade fireworks, startling the birds into a panic flight. On New Year's Eve 2011, a few hours before entering into 2012, blackbirds again were reported to be falling to the ground in Beebe. Several hundred had plunged to their deaths according to the local television station KATV which also reported that its radar had shown a "large mass" over the town.

In his 1997 article “Dead Cows I've Known”,Dean Trimboli T(1997), Dead Cows I've Known. cattle mutilation researcher Charles T. Oliphant speculates cattle mutilation to be the result of covert research into emerging cattle diseases, and the possibility they could be transmitted to humans. Oliphant posits the NIH, CDC, or other federally funded bodies, may be involved, and they are supported by the US military. Part of his hypothesis is based on allegations that human pharmaceuticals have been found in mutilated cattle, and on the necropsies that show cattle mutilations commonly involve areas of the animal that relate to “input, output and reproduction”.

This number still keeps them on track for removal from the endangered species list, although just barely. Necropsies of dead sea otters indicate diseases, particularly Toxoplasma gondii and acanthocephalan parasite infections, are major causes of sea otter mortality in California. The Toxoplasma gondii parasite, which is often fatal to sea otters, is carried by wild and domestic cats and may be transmitted by domestic cat droppings flushed into the ocean via sewage systems. Although disease has clearly contributed to the deaths of many of California's sea otters, it is not known why the California population is apparently more affected by disease than populations in other areas.

Orcas in the wild live at higher latitudes, meaning less intense sun, and spend more time in deeper, darker waters. While the effects of prolonged UV exposure on orcas' skin is uncertain, since captive orca necropsies are extremely secretive, it is thought that prolonged exposure to UV rays on unprotected skin would have the same negative effects such as melanoma (skin cancer) on orcas as it does on humans. The original Namu developed a bacterial infection which damaged his nervous system, causing him to become unresponsive to people. During his illness he charged full-speed into the wire mesh of his pen, thrashed violently for a few minutes and then died.

It was not until the 1980s that the infection could be formally identified. In 2000, equine specialists studying the two necropsies concluded that Phar Lap probably died of duodenitis-proximal jejunitis, an acute bacterial gastroenteritis. Phar Lap's skin was preserved by Louis Paul Jonas and is now exhibited as a taxidermy mount by Melbourne Museum. In 2006, Australian Synchrotron Research scientists said it was almost certain Phar Lap was poisoned with a large single dose of arsenic in the hours before he died, perhaps supporting the theory that Phar Lap was killed on the orders of US gangsters, who feared the Melbourne Cup-winning champion would inflict big losses on their illegal bookmakers.

Necropsies showed their insides were lined with burns and festering sores from exposure to high concentrations of copper, cadmium, and arsenic. (Levels of copper are high enough that Montana Resources has mined copper directly from the water.) On November 28, 2016, several thousand snow geese died after a large flock landed in the pit's water to avoid a snow storm. Immediately after the event, officials made efforts to scare birds away and prevent more from landing in the area. An official report issued in 2017 by the U.S. Fish and Wildlife Service found that the 3,000 to 4,000 snow geese that died at the Berkeley Pit were killed by exposure to sulfuric acid and heavy metals.

LLOV was discovered in 2011 in Schreibers's long- fingered bats (species Miniopterus schreibersii) that were found dead in Cueva del Lloviu back in 2002, Asturias, Spain, as well as in caves in Spanish Cantabria and in caves in France and Portugal. It has not yet been proven that the virus is the etiological agent of a novel bat disease, but healthy Schreibers' long-fingered bats were not found to contain traces of the viruses, thereby at least suggesting that the virus may be pathogenic for certain bats. Necropsies of dead bats did not reveal macroscopic pathology, but microscopic examination suggested viral pneumonia. No information is available about whether or not LLOV infects humans.

Nonetheless, some continue to view the horses as an invasive species which is not suitable in a protected region where ecological integrity should be preserved according to the National Parks Act. A study published in 2019 found that the Sable Island horses had about three times the level of parasite eggs in their fecal material than domesticated horses, averaging 1500 eggs per gram. These included a parasitic lungworms that caused respiratory diseases; the horses also suffered from reproductive diseases. Necropsies of carcasses inspected in 2017 and 2018 showed that young horses died of starvation and hypothermia, particularly during extreme winters, as they would not have a sufficient reserve of body fat and suitable vegetation is sparse on the island during winter.

WEE was discovered in 1930 when a number of horses in the San Joaquin Valley of California, USA died of a mysterious encephalitis. Karl Friedrich Meyer investigated but was not able to isolate the pathogen from necropsies of horses that had been dead for some time and needed samples from an animal in the earlier stages of disease. When the team heard of a horse that appeared to have encephalitis, its owner threatened to shoot the scientists. However Meyer was able to convince the farmer's wife that the horse was dying anyway, and to secretly signal him when the farmer was asleep in exchange for $20 (as this was during the Great Depression, this was a substantial amount of money).

At about this time during the fall of 2003, colleagues who had been provided the prepublication draft of the AFT analysis paper were performing necropsies on pigs that had been dosed with ETCs. They noted the intestinal tracts of these pigs showed large numbers of intestinal microgranulomas, each encasing an ETC setal fragment. Discussing rumors of these findings with Dr. Terry Fitzgerald, he noted that similar intestinal microgranulomas had been observed previously in ETC-dosed rats by colleagues experimenting with ETCs, and he shared some H and E section of such a rat intestinal ETC setal microgranuloma slides for inclusion in a second paper. The SPSE hypothesis included intestinal penetration and presumably lethal peritonitis as one logical outcome of intestinal exposure to ETC septic penetrating setal fragments.

The most common organic postpartum psychosis is infective delirium. This was mentioned by Hippocrates Hippocrates (5th Century BC) Epidemics, book III, volume 1, pages 280-283, in the edition translated by W H S Jones, 1931. : there are 8 cases of puerperal or post-abortion sepsis among the 17 women in the 1st and 3rd books of epidemics, all complicated by delirium. In Europe and North America the foundation of the metropolitan maternity hospitals, together with instrumental deliveries and the practice of attending necropsies, led to epidemics of streptococcal puerperal fever, resulting in maternal mortality rates up to 10%. The peak was about 1870, after which antisepsis and asepsis gradually brought them under control. These severe infections were often complicated by delirium, but it was not until the nosological advances of Chaslin Chaslin P (1895) Confusion Mentale Primitive, Stupidité, Démence aiguë, Stupeur Primitive.

In general, cognitive support diets are formulated to include nutrients that have a known role in brain development, function and/or maintenance, with the goal of improving and preserving mental processes such as attentiveness, short-term and long-term memory, learning, and problem solving. Currently, there is very little conclusive research available regarding cat cognition as standardized tests for evaluating cognitive ability are less established and less reliable than cognitive testing apparatus used in other mammalian species, like dogs. Much of what is known about feline cognition has been inferred from a combination of owner-reported behaviour, brain necropsies, and comparative cognitive neurology of related animal models. Cognition claims appear primarily on kitten diets which include elevated levels of nutrients associated with optimal brain development, although there are now diets available for senior cats that include nutrients to help slow the progression of age-related changes and prevent cognitive decline.

An update to this study found that toxoplasmosis had killed nine out of 38 post-weaning age Hector's and Māui dolphins found washed up or floating at-sea, and that were not too autolised to determine a cause of death. Of these nine, six were reproductive females, tentatively indicating that this demographic may be more suspectible to infection.. In New Zealand, the domestic house cat is the only known definitive host for toxoplasma, and Hector's and Maui dolphins are thought to become infected as a result of their preference for turbid coastal waters near river mouths, where toxoplasma oocyst densities are likely to be relatively high. Brucellosis is a notable bacterial disease of Hector's and Māui dolphins that can cause late pregnancy abortion in terrestrial mammals, and has been found in a range of cetacean species elsewhere.. Brucellosis has been determined from necropsies to have killed both Hector's and Māui dolphins and to have caused reproductive disease, indicating that it may affect the reproductive success of both sub- species.
