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]

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]

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]
