Papovaviridae

 [pah-po´vah-vir″ĭ-de]
the papovaviruses, a family of DNA viruses having a virion 40 to 55 nm in diameter with 72 capsomers in skew arrangement. Replication and assembly occur in the nucleus; virions are released by cell destruction. Host range is generally narrow; transmission is by contact or by airborne particles, and many species are oncogenic. There are two genera, Papovavirus and Polyomavirus.

Pa·po·va·vir·i·dae

(pă-pō'vă-vir'i-dē),
A family of small, antigenically distinct viruses that replicate in nuclei of infected cells; most have oncogenic properties. Virions are 45-55 nm in diameter, nonenveloped, and ether resistant; capsids are icosahedral with 72 capsomeres, and they contain double-stranded circular DNA (MW 3-5 × 106). The family includes two genera, Papillomavirus and Polyomavirus.

Papovaviridae

a family of viruses containing two genera: Papillomavirus, which cause warts in various species, and Polyomavirus, which cause tumors in rodents (mice, hamsters) and have been extensively studied as models of viral oncogenesis. Virions are icosahedral, 45-55 nm in diameter, naked, ether-resistant and contain a supercoiled circular double-stranded DNA genome of ∼8 kilobases.
