Papovaviridae /Pa·po·va·vi·ri·dae/ (pah-po″vah-vir´ĭ-de) the papovaviruses: a family of DNA viruses, many of which are oncogenic or potentially oncogenic; it includes two subfamilies, Papillomavirinae and Polyomavirinae.
Papovaviridae [pah-po´vah-vir″ĭ-de]
papoose board (papoos´),
Pa·po·va·vir·i·dae (p -p  v-vîr  -d )n. A family of small antigenically distinct viruses, comprising the genera Papillomavirus and Polyomavirus, that replicate in nuclei of infected cells. |
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.
papoose board (papoos´),
n a board used to stabilize the position of a pediatric patient, or a patient with limited psychomotor control. It comes in various sizes and has soft flaps that surround and hold the patient.
)
Papoose board.
Papovaviridae
n.pl a major deoxyribonucleic acid virus to which the papillomavirus and polyomavirus belong. Viruses in this family have a double-stranded, supercoiled, circular molecular structure with icosahedral symmetry.
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.
