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.
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
Polyomaviridae is a family of viruses.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).
Wild birds carry a variant of H5N1 called D1.1 or D1.2. The virus that infected the Canadian teenager was found to be closely related to those circulating in local poultry, belonging to the D.1.1 ...
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 ...
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 ...
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 ...
Murine polyomavirus (MPyV), described in the 1950s, was the first polyomavirus discovered and can cause tumors in rodents. MPyV has three early proteins; in addition to LTag and STag it also expresses middle tumor antigen , which is primarily responsible for the virus's transforming activity.
