Aveparvovirus is a genus of viruses, in the subfamily Parvovirinae of the virus family Parvoviridae.[1][2] There are 11 species in this genus.[3] Diseases associated with this genus include: enteric disease and malabsorption syndrome.[4][5]
Taxonomy
[edit]The genus contains the following species, listed by scientific name and followed by the exemplar virus of the species:[3][6]
- Aveparvovirus anseriform1, Mute swan feces associated aveparvovirus
- Aveparvovirus avian1, Bird parvovirus strain Bir-01-1
- Aveparvovirus columbid1, Pigeon parvovirus 1

Structure
[edit]Viruses in Aveparvovirus 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.[4]
| Genus | Structure | Symmetry | Capsid | Genomic arrangement | Genomic segmentation |
|---|---|---|---|---|---|
| Aveparvovirus | Icosahedral | T=1 | Non-enveloped | Linear | None |
Life cycle
[edit]Viral replication is nuclear. Entry into the host cell is achieved by attachment to host receptors, and is probably driven by clathrin-mediated endocytosis. Replication follows the rolling-hairpin model. DNA-templated transcription, with some alternative splicing mechanism is the method of transcription. Its cell exit strategy remains to be determined but probably involves cell lysis, as seen for other parvoviruses,. Birds serve as the natural host.[4]
| Genus | Host details | Tissue tropism | Entry details | Release details | Replication site | Assembly site | Transmission |
|---|---|---|---|---|---|---|---|
| Aveparvovirus | Birds | uncertain | Clathrin-mediated endocytosis | uncertain | Nucleus | Nucleus | Aerosol; oral-fecal |
