Brevidensovirus[1] is a genus of viruses in subfamily Densovirinae[2] of the family Parvoviridae.[3][4] Mosquitoes serve as natural hosts. There are currently only two species in this genus including the type species Dipteran brevidensovirus 1.[5][6]
Taxonomy
Group: ssDNA
- Family: Parvoviridae
- Sub-Family: Densovirinae
- Genus: Brevidensovirus
- Dipteran brevidensovirus 1
- Dipteran brevidensovirus 2
Structure
Viruses in genus Brevidensovirus are non-enveloped and have T=1 icosahedral symmetry. The diameter is around 21-22 nm. Genomes are linear, around 4kb in length.[5][3]
| Genus | Structure | Symmetry | Capsid | Genomic arrangement | Genomic segmentation |
|---|---|---|---|---|---|
| Brevidensovirus | 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.[5][3]
| Genus | Host details | Tissue tropism | Entry details | Release details | Replication site | Assembly site | Transmission |
|---|---|---|---|---|---|---|---|
| Brevidensovirus | Insects: diptera | None | Clathrin-mediated endocytosis | Cell lysis | Nucleus | Nucleus | Unknown |
