n.

A family of small antigenically distinct viruses, comprising the genera Papillomavirus and Polyomavirus, that replicate in nuclei of infected cells.

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.
