The Big Picture Book of Viruses: Poxviridae

ICTVdB Data

Taxonomy:

Taxonomic structure of the family.

Subfamily Chondropoxvirinae
Subfamily Entomopoxvirinae
Unclassified viruses

Genome:

Virions contain one molecule of linear double stranded DNA.

Total genome length is 130000-375000 nt. Genome sequence has terminal repeated sequences; reiterated inverted terminal sequences which are tandemly repeated; repeated at both ends. Guanine + cytosine ratio 35-64 %, or 20 % (for Entomopoxviruses). Double stranded DNA covalently cross-linked at the end.

Host:

Virus infects invertebrates and vertebrates.

Morphology:

Virions enveloped; slightly pleomorphic; ovoid, or brick-shaped; 140-260 nm in diameter; 220-450 nm long. Composed of an external coat containing lipid and tubular or globular protein structures enclosing one or two lateral bodies and a core, which contains the genome. Nucleocapsids brick-shaped to ovoid. Core usually biconcave with two lateral bodies.
