Brevihamaparvovirus

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

Taxonomy

The genus contains the following species, listed by scientific name and followed by the exemplar virus of the species:^[4][5]

• Brevihamaparvovirus dipteran1, Anopheles gambiae densovirus
• Brevihamaparvovirus dipteran2, Aedes albopictus densovirus 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]

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]
