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/ any member of the subfamily Polyomavirinae.

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.

polyomavirus

(pŏl′ē-ō′mə-vī′rəs)
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.
