Brevihamaparvovirus

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

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]
