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]
| Genus | Structure | Symmetry | Capsid | Genomic arrangement | Genomic segmentation |
|---|---|---|---|---|---|
| Copiparvovirus | Icosahedral | T=1 | Non-enveloped | Linear | None |
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]
| Genus | Host details | Tissue tropism | Entry details | Release details | Replication site | Assembly site | Transmission |

| Copiparvovirus | Ungulates | Not defined | Clathrin-mediated endocytosis | Lysis | Nucleus | Nucleus | Unknown |
