A family of large complex viruses, with a marked affinity for skin tissue, which are pathogenic for humans and other animals. Virions are large, up to 250 × 400 nm, and enveloped (double membranes). Replication occurs entirely in the cytoplasm of infected cells. Capsids are of complex symmetry and contain double-stranded DNA (MW 160 × 106), the nucleoprotein antigen being common to all members of the family. Several genera are recognized, including: Orthopoxvirus, Avipoxvirus, Capripoxvirus, Leporipoxvirus, and Parapoxvirus.
Poxviridae/Pox·vi·ri·dae/ (poks″vir´ĭ-de) the poxviruses: a family of DNA viruses with a double-stranded DNA genome, including viruses causing smallpox and the pox diseases of other animals; the two subfamilies are Chordopoxvirinae (poxviruses of vertebrates) and Entomopoxvirinae (poxviruses of insects).
A family of large, complex viruses, with a marked affinity for skin tissue, which are pathogenic for humans and other animals; a number of genera are recognized, including, Orthopoxvirus, Avipoxvirus, Capripoxvirus, Leporipoxvirus, and Parapoxvirus.
a family of viruses, the members of which are large, brick- or oval-shaped particles containing a double-strand DNA genome that replicate in the cytoplasm of cells. There are six genera in the family: (1) Orthopoxvirus, which includes alastrim, buffalopox, camelpox, cowpox, ectromelia (mousepox), horsepox, monkeypox, rabbitpox, vaccinia, variola; (2) Avipoxvirus, closely related viruses that include canarypox, fowlpox, juncopox, lovebirdpox, pigeonpox, quailpox, sparrowpox, starlingpox, turkeypox and others; (3) Capripoxvirus, which includes goatpox, lumpy skin disease, and sheeppox viruses; (4) Leporipoxvirus, which includes squirrel, hare, and rabbit (Shope) fibroma viruses and myxoma viruses; (5) Suipoxvirus, which includes swinepox virus; (6) Parapoxvirus, which includes contagious ecthyma, bovine papular stomatitis, sealionpox and pseudocowpox viruses. There are also unclassified poxviruses isolated from cats, elephants, lions, raccoons and gerbils.
