Brevidensovirus

Brevidensovirus[1] is a genus of viruses in subfamily Densovirinae[2] of the family Parvoviridae.[3][4] Mosquitoes serve as natural hosts. There are currently only two species in this genus including the type species Dipteran brevidensovirus 1.[5][6]

Structure

Viruses in genus Brevidensovirus are non-enveloped and have T=1 icosahedral symmetry. The diameter is around 21-22 nm. Genomes are linear, around 4kb in length.[5][3]

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.[5][3]
