Brevihamaparvovirus
Brevihamaparvovirus is a genus of viruses in subfamily Hamaparvovirinae of the family Parvoviridae.[1][2] Mosquitoes serve as natural hosts. There are two species in this genus.[3][4]

Taxonomy
The following two species are assigned to the genus:[4]
- Dipteran brevihamaparvovirus 1
- Dipteran brevihamaparvovirus 2
Structure
Viruses in genus Brevihamaparvovirus are non-enveloped and have T=1 icosahedral symmetry. The diameter is around 21-22 nm. Genomes are linear, around 4kb in length.[3][1]
| Genus | Structure | Symmetry | Capsid | Genomic arrangement | Genomic segmentation |
|---|---|---|---|---|---|
| Brevihamaparvovirus | 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. Mosquitoes serve as the natural host.[3][1]
| Genus | Host details | Tissue tropism | Entry details | Release details | Replication site | Assembly site | Transmission |
|---|---|---|---|---|---|---|---|
| Brevihamaparvovirus | Insects: diptera | None | Clathrin-mediated endocytosis | Cell lysis | Nucleus | Nucleus | Unknown |
