Copiparvovirus is a genus of viruses in subfamily Parvovirinae of the virus family Parvoviridae.^[1][2] Pigs and cows are known to serve as natural hosts. There are seven species in this genus.^[3][4][5]

Taxonomy

The following seven species are assigned to the genus:^[5]

• Pinniped copiparvovirus 1
• Ungulate copiparvovirus 1
• Ungulate copiparvovirus 2
• Ungulate copiparvovirus 3
• Ungulate copiparvovirus 4
• Ungulate copiparvovirus 5
• Ungulate copiparvovirus 6

Structure

Viruses in genus Copiparvovirus are non-enveloped, with icosahedral and round geometries, and T=1 symmetry. The diameter is around 18-26 nm. Genomes are linear, around 6kb in length.^[2][4]

Life cycle

Viral replication is nuclear. Entry into the host cell is achieved by attachment to host receptors, which mediates clathrin-mediated endocytosis. Replication follows the rolling-hairpin model. DNA-templated transcription, with some alternative splicing mechanism is the method of transcription. The virus exits the host cell by nuclear pore export. Bovine serve as the natural host.^[4]
