Brevipenbrevirus is a genus of viruses in subfamily Penbrevirinae of the family Parvoviridae. Mosquitoes serve as natural hosts. There are four species in this genus.[1][2]
Taxonomy
[edit]The genus contains the following species, listed by scientific name and followed by the exemplar virus of the species:[2][3]
- Brevipenbrevirus dipteran1, Anopheles gambiae densovirus
- Brevipenbrevirus dipteran2, Aedes albopictus densovirus 2
- Brevipenbrevirus orthopteran1, Acheta domesticus segmented densovirus
- Brevipenbrevirus orthopteran2, Soybean thrips denso-like virus 1
Structure
[edit]Viruses in genus Brevipenbrevirus are non-enveloped and have T=1 icosahedral symmetry. The diameter is around 21-22 nm. Genomes are linear, around 4kb in length.[1][4]
| Genus | Structure | Symmetry | Capsid | Genomic arrangement | Genomic segmentation |
|---|---|---|---|---|---|
| Brevipenbrevirus | 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, which mediates clathrin-mediated endocytosis. Replication follows the rolling-hairpin model. DNA-templated transcription, with some alternative splicing mechanism is the method of transcription. Mosquitoes serve as the natural host.[1][4]
| Genus | Host details | Tissue tropism | Entry details | Release details | Replication site | Assembly site | Transmission |
|---|---|---|---|---|---|---|---|
| Brevipenbrevirus | Insects: diptera | None | Clathrin-mediated endocytosis | Cell lysis | Nucleus | Nucleus | Unknown |
