SARS-CoV-2 In Mink
Both the American mink and the European mink have shown high susceptibility to SARS-CoV-2 since the earliest stages of the COVID-19 pandemic, first in mink farms across Europe, followed by mink farms in the United States. Mortality has been extremely high among mink, with 35–55% of infected adult animals dying from COVID-19 in a study of farmed mink in the U.S. state of Utah. In November 2020, in Denmark, it was announced that all mink nationwide were being slaughtered due to reports that a mutated virus was being passed from mink to humans via mink farms, and that at least 12 human infections had been discovered in Northern Jutland. While the State Serum Institute (SSI, ) suggested that this mutation was no more dangerous than other coronaviruses, SSI head Kåre Mølbak warned that the mutation could impact the development and effectiveness of COVID-19 vaccines. The first known transmission of SARS-CoV-2 among wild mink was reported in Utah, which researchers believed was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SARS-CoV-2 In White-tailed Deer
Blood samples gathered by USDA researchers in 2021 showed that 40% of sampled white-tailed deer demonstrated evidence of SARS-CoV-2 antibodies, with the highest percentages in Michigan, at 67%, and Pennsylvania, at 44%. A later study by Penn State University and wildlife officials in Iowa showed that up to 80 percent of Iowa deer sampled from April 2020 through January 2021 had tested positive for active SARS-CoV-2 infection, rather than solely antibodies from prior infection. This data, confirmed by the National Veterinary Services Laboratory, alerted scientists to the possibility that white-tailed deer had become a natural reservoir for the coronavirus, serving as a potential "variant factory" for eventual retransmission back into humans. In a March 2022 joint statement regarding animal monitoring, the World Health Organization (WHO), Food and Agriculture Organization (FAO), and World Organisation for Animal Health (OIE) specifically cited white-tailed deer as an example of a ...

American Mink
The American mink (''Neogale vison'') is a semiaquatic species of mustelid native to North America, though human intervention has expanded its range to many parts of Europe, Asia and South America. Because of range expansion, the American mink is classed as a least-concern species by the IUCN. The American mink was formerly thought to be the only extant member of the genus ''Neovison'' following the extinction of the sea mink (''N. macrodon''), but recent studies, followed by taxonomic authorities, have reclassified it and the sea mink within the genus ''Neogale'', which also contains a few New World weasel species. The American mink is a carnivore that feeds on rodents, fish, crustaceans, frogs, and birds. In its introduced range in Europe it has been classified as an invasive species linked to declines in European mink, Pyrenean desman, and water vole populations. It is the animal most frequently farmed for its fur, exceeding the silver fox, sable, marten, and skunk in econo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Histidine
Histidine (symbol His or H) is an essential amino acid that is used in the biosynthesis of proteins. It contains an α-amino group (which is in the protonated –NH3+ form under biological conditions), a carboxylic acid group (which is in the deprotonated –COO− form under biological conditions), and an imidazole side chain (which is partially protonated), classifying it as a positively charged amino acid at physiological pH. Initially thought essential only for infants, it has now been shown in longer-term studies to be essential for adults also. It is encoded by the codons CAU and CAC. Histidine was first isolated by Albrecht Kossel and Sven Gustaf Hedin in 1896. It is also a precursor to histamine, a vital inflammatory agent in immune responses. The acyl radical is histidyl. Properties of the imidazole side chain The conjugate acid (protonated form) of the imidazole side chain in histidine has a p''K''a of approximately 6.0. Thus, below a pH of 6, the imidazole ring ...

Mink
Mink are dark-colored, semiaquatic, carnivorous mammals of the genera ''Neogale'' and '' Mustela'' and part of the family Mustelidae, which also includes weasels, otters, and ferrets. There are two extant species referred to as "mink": the American mink and the European mink. The extinct sea mink was related to the American mink but was much larger. The American mink's fur has been highly prized for use in clothing. Their treatment on fur farms has been a focus of animal rights and animal welfare activism. American mink have established populations in Europe (including Great Britain and Denmark) and South America. Some people believe this happened after the animals were released from mink farms by animal rights activists, or otherwise escaped from captivity. In the UK, under the Wildlife and Countryside Act 1981, it is illegal to release mink into the wild. In some countries, any live mink caught in traps must be humanely killed. American mink are believed by some to have c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
COVID-19 Pandemic And Animals
The COVID-19 pandemic has affected animals directly and indirectly. SARS-CoV-2, the virus that causes COVID-19, is zoonotic, which likely to have originated from animals such as bats and pangolins. Human impact on wildlife and animal habitats may be causing such spillover events to become much more likely. The largest incident to date was the culling of 14 to 17 million mink in Denmark after it was discovered that they were infected with a mutant strain of the virus. While research is inconclusive, pet owners reported that their animals contributed to better mental health and lower loneliness during COVID-19 lockdowns. However, contact with humans infected with the virus could have adverse effects on pet animals. Background SARS-CoV-2 is believed to have zoonotic origins and has close genetic similarity to bat coronaviruses, suggesting it emerged from a bat-borne virus. Cases A small number of pet animals have been infected. There have been several cases of zoo anima ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Animals That Can Get SARS-CoV-2
Various animals have been proven to be able to become infected with SARS-CoV-2, the virus that causes COVID-19. The Centers for Disease Control and Prevention has stated that it is a low risk that the virus would spread from animals to people. Coronaviruses are common among some animal species, but this list only shows those who have been proven to carry the virus that causes COVID-19. Most types of animals that can get the virus have not been proven to be able to spread it back to humans.

Methionine
Methionine (symbol Met or M) () is an essential amino acid in humans. As the precursor of other amino acids such as cysteine and taurine, versatile compounds such as SAM-e, and the important antioxidant glutathione, methionine plays a critical role in the metabolism and health of many species, including humans. It is encoded by the codon AUG. Methionine is also an important part of angiogenesis, the growth of new blood vessels. Supplementation may benefit those suffering from copper poisoning. Overconsumption of methionine, the methyl group donor in DNA methylation, is related to cancer growth in a number of studies. Methionine was first isolated in 1921 by John Howard Mueller. Biochemical details Methionine (abbreviated as Met or M; encoded by the codon AUG) is an α-amino acid that is used in the biosynthesis of proteins. It contains a carboxyl group (which is in the deprotonated −COO− form under biological pH conditions), an amino group (which is in the protonated fo ...

Isoleucine
Isoleucine (symbol Ile or I) is an α-amino acid that is used in the biosynthesis of proteins. It contains an α-amino group (which is in the protonated −NH form under biological conditions), an α-carboxylic acid group (which is in the deprotonated −COO form under biological conditions), and a hydrocarbon side chain with a branch (a central carbon atom bound to three other carbon atoms). It is classified as a non-polar, uncharged (at physiological pH), branched-chain, aliphatic amino acid. It is essential in humans, meaning the body cannot synthesize it, and must be ingested in our diet. Isoleucine is synthesized from pyruvate employing leucine biosynthesis enzymes in other organisms such as bacteria. It is encoded by the codons AUU, AUC, and AUA. Metabolism Biosynthesis As an essential nutrient, it is not synthesized in the body, hence it must be ingested, usually as a component of proteins. In plants and microorganisms, it is synthesized via several steps, startin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
