Brevipenbrevirus
Virus classification
(unranked): Virus
Realm: Floreoviria

Order: Piccovirales
Family: Parvoviridae
Subfamily: Penbrevirinae
Genus: Brevipenbrevirus

Brevipenbrevirus is a genus of viruses in subfamily Penbrevirinae of the family Parvoviridae. Mosquitoes serve as natural hosts. There are four species in this genus.[1][2]

Taxonomy

The genus contains the following species, listed by scientific name and followed by the exemplar virus of the species:[2][3]

  • Brevipenbrevirus dipteran1, Anopheles gambiae densovirus
  • Brevipenbrevirus dipteran2, Aedes albopictus densovirus 2
  • Brevipenbrevirus orthopteran1, Acheta domesticus segmented densovirus
  • Brevipenbrevirus orthopteran2, Soybean thrips denso-like virus 1

Structure

Viruses in genus Brevipenbrevirus are non-enveloped and have T=1 icosahedral symmetry. The diameter is around 21-22 nm. Genomes are linear, around 4kb in length.[1][4]

Brevipenbrevirus 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.[1][4]
