Papillomaviridae ''Papillomaviridae'' is a family of non- enveloped DNA viruses whose members are known as papillomaviruses. Several hundred species of papillomaviruses, traditionally referred to as "types", have been identified infecting all carefully inspected ...

''. Rabbits serve as natural hosts. There are two species in this genus. Diseases associated with this genus include: cutaneous and mucosal lesions.

Taxonomy

The following two species are assigned to the genus: * '' Kappapapillomavirus 1'' * '' Kappapapillomavirus 2''

Structure

Viruses in ''Kappapapillomavirus'' are non-enveloped, with icosahedral geometries, and T=7 symmetry. The diameter is around 52-55 nm. Genomes are circular, around 8kb in length. The genome codes for 6 proteins, and has 6, 8 open reading frames.

Life cycle

Viral replication is nuclear. Entry into the host cell is achieved by attachment of the viral proteins to host receptors, which mediates endocytosis. Replication follows the dsDNA bidirectional replication model. DNA-templated transcription, with some alternative splicing mechanism is the method of transcription. The virus exits the host cell by nuclear envelope breakdown. Rabbits serve as the natural host. Transmission routes are contact.
