Polyomaviridae is a family of viruses whose natural hosts are primarily mammals and birds. [1] [2] As of 2024, there are eight recognized genera. [3]Fourteen species are known to infect humans, while others, such as Simian Virus 40, have been identified in humans to a lesser extent.
Mammals and birds serve as natural hosts. There are currently 13 species in this family, divided among 1 genera, Polyomavirus (type species Simian virus 40). Diseases associated with this family include: JCPyV: progressive multifocal leukoencephalopathy; BKPyV: mild respiratory infection.
Murine polyomavirus (also known as mouse polyomavirus, Polyomavirus muris, or Mus musculus polyomavirus 1, and in older literature as SE polyoma or parotid tumor virus; abbreviated MPyV) is an unenveloped double-stranded DNA virus of the polyomavirus family. The first member of the family discovered, it was originally identified by accident in ...
The patient was infected with the D1.1 genotype of the virus that was recently detected in wild birds and poultry in the United States, and not the B3.13 genotype detected in dairy cows, human ...
The bird flu virus strain that is rampant among dairy cows in the U.S. may only need one mutation for it to be able to spread among humans, according to a study published this week.
A map of the murine polyomavirus genome, indicating the early genes (LTag, MTag, and STag) at right in blue and the late genes (the viral capsid proteins) at left in red. . Each region is transcribed as a single messenger RNA and alternatively spliced to express multiple proteins; the exons are shown as thickened lin
There have been no reports in the European Union of bird flu infecting a human or cow but research is ongoing on the virus's transmission, an EU official said on Thursday, one day after U.S ...
The migratory nature of birds poses a distinct danger for the spreading of diseases. Without being affected by the infectious agent, birds can act as vectors in spreading psittacosis, salmonellosis, campylobacteriosis, mycobacteriosis, avian influenza, giardiasis and cryptosporidiosis. These zoonotic diseases can be transmitted to humans.
