Brevihamaparvovirus Explained

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:

• 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.^[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.^[1]
