Parvoviridae Parvoviruses are a family of animal viruses that constitute the family ''Parvoviridae''. They have linear, single-stranded DNA (ssDNA) genomes that typically contain two genes encoding for a replication initiator protein, called NS1, and the pr ...

''. Mosquitoes serve as natural hosts. There are three species in this genus.

Taxonomy

The genus contains the following species, listed by scientific name and followed by the exemplar virus of the species: * ''Brevihamaparvovirus dipteran1'', Anopheles gambiae densovirus * ''Brevihamaparvovirus dipteran2'', Aedes albopictus densovirus 2 * ''Brevihamaparvovirus orthopteran1'', Acheta domesticus segmented densovirus

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.

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.
