Pol·y·o·ma·vi·rus

(pol'ē-ō'mă-vī'rŭs),
A genus of viruses (family Papovaviridae) containing DNA (MW 3 × 106), having virions about 45 nm in diameter, and including viruses oncogenic for animals; includes the polyoma virus of rodents, vacuolating viruses (SV40) of primates, and the BK and JC viruses of humans.

Polyomavirus

/Poly·o·ma·vi·rus/ (-vi″rus) polyomaviruses; a genus of viruses of the subfamily Polyomavirinae (family Papovaviridae) that induce tumors in experimental animals; two, BK virus and JC virus, infect humans, and others, including simian virus 40 (SV40), infect other mammals.

n.
Any of a genus of DNA viruses that infect birds and mammals and induce tumors in certain rodents.

polyomavirus

A small icosahedral, double-stranded oncogenic DNA virus of the Papovaviridae family, which may be used to induce experimental tumours in mice. The polyomavirus may be identified in both domestic and wild rodents.

Polyomavirus

a genus in the family Papovaviridae that includes simian virus 40 and polyomavirus, both of which cause tumors in rodents and have been extensively studied as models of oncogenic DNA viruses. A polyoma-like virus may cause an acute disease in psittacine birds.

PyVs are small, circular, double-stranded DNA viruses, and analysis of the RacPyV genome showed characteristic organization for Polyomaviridae (Figure 2) (6).
Taxonomical developments in the family Polyomaviridae.
GenBank reference sequences of other members of the family Polyomaviridae used were JCPyV (NC_001699), BKPyV (NC_001538), KIPyV (NC_009238), WuPyV (NC_009539), MCPyV (NC_010277), SV40 (NC_001669), TSPyV (NC_014361), and LPV (M30540).

Pairwise amino acid identity was 100% between IPPyV and HPyV9 proteins, 72%-80% between IPPyV and LPV proteins, and much lower for other known family Polyomaviridae members (Table).
We compared the secondary structure of VP1 from LPV and HPyV9 because the external capsid protein of Polyomaviridae is known to interact with the cell receptor and because antibodies cross-reacting with LPV VP1 have been detected in a large proportion of humans.
The recent description of new human viruses belonging to the family Polyomaviridae suggests that some of these viruses share the cutaneous tropism of P-HPV and y-HPV.
To the Editor: Two new members of the Polyomaviridae family, provisionally named Karolinska Institutet virus (KIPyV) and Washington University virus (WUPyV), have been recently discovered (1,2).
