The virions are generally enveloped though the intracellular mature virion form of the virus, which contains a different envelope, and is also infectious. They vary in their shape depending upon the species, but are generally shaped like a brick or as an oval form similar to a rounded brick because they are wrapped by the endoplasmic reticulum. The virion is exceptionally large, around 200 nm in diameter and 300 nm in length, and carries its genome in a single, double-stranded segment of DNA.[3] Genomes are linear, around 130-375kb in length.[1]

Taxonomy[edit]
The classification in this subfamily is based on the morphology, nucleic acid type, mode of replication, host organisms, and type of disease caused.
Nine genera in this subfamily are recognized; also, a number of species have not yet been assigned to a genus.
The species in the genus Avipoxvirus infect birds; those in the genera Caiman poxvirus and Crocodylipoxvirus both infect crocodilians.
The other genera in this subfamily infect mammals.
The following genera are recognized:[2]
- Avipoxvirus
- Capripoxvirus
- Centapoxvirus
- Cervidpoxvirus
- Crocodylidpoxvirus
- Leporipoxvirus
- Macropopoxvirus
- Molluscipoxvirus
- Mustelpoxvirus
- Orthopoxvirus
- Oryzopoxvirus
- Parapoxvirus
- Pteropopoxvirus
- Salmonpoxvirus
- Sciuripoxvirus
- Suipoxvirus
- Vespertilionpoxvirus
- Yatapoxvirus
