GX_P2V is a COVID-19 mutant strain that is fatal to humanized mice with the hACE2 gene. [ 1 ] The Chinese government has been performing tests on GX_P2V and has published a new study. [ 2 ] “ This underscores a spillover risk of GX_P2V into humans and provides a unique model for understanding the pathogenic mechanisms of SARS-CoV-2 related ...
The land flatworm Humbertium covidum The caddisfly Potamophylax coronavirus (in alphabetical order of genera) Achilia covidia Kurbatov, Cuccodoro & Sabella, 2021 (Insect, Coleoptera, Staphylinidae) – "the epithet of this new species refers to the COVID-19 pandemic and the periods of quarantine during which this study was carried out by the authors".

A mouse (pl.: mice) is a small rodent. Characteristically, mice are known to have a pointed snout, small rounded ears, a body-length scaly tail, and a high breeding rate. The best known mouse species is the common house mouse (Mus musculus). Mice are also popular as pets. In some places, certain kinds of field mice are locally common. They are ...
Dozens of captive animal species have been found infected or proven able to be experimentally infected with SARS-CoV-2, the virus that causes COVID-19. The virus has also been found in over a dozen wild animal species. Most animal species that can get the virus have not been proven to be able to spread it back to humans.
Coronavirus diseases are caused by viruses in the coronavirus subfamily, a group of related RNA viruses that cause diseases in mammals and birds. In humans and birds, the group of viruses cause respiratory tract infections that can range from mild to lethal.
After cross-species transmission of a virus, rapid evolution and positive selection are expected. [47] Several studies found only weak signs of adaptive evolution early in the COVID-19 pandemic. [c] Kang et al. wrote that SARS-CoV-2 had exhibited relatively little genetic variation by 2021. [47]
Mouse hepatitis virus (MHV), which is a member of the species Murine coronavirus, [143] causes an epidemic murine illness with high mortality, especially among colonies of laboratory mice. [144] Prior to the discovery of SARS-CoV, MHV was the best-studied coronavirus both in vivo and in vitro as well as at the molecular level.
