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]
The following seven species are assigned to the genus:
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]

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]
