Subfamily: Densovirinae
Genus: Hepandensovirus
Type Species
  • Decapod hepandensovirus 1

Hepandensovirus is a genus of viruses, in the family Parvoviridae, in the subfamily Densovirinae. Insects and shrimps serve as natural hosts. There is currently only one species in this genus: the type species Decapod hepandensovirus 1. Diseases associated with this genus include: causes mortalities in early larval and postlarval stages of shrimps.[1][2]

Structure

Viruses in Hepandensovirus are non-enveloped, with icosahedral and round geometries, and T=1 symmetry. The diameter is around 21-22 nm. Genomes are linear, around 6kb 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. The virus exits the host cell by nuclear pore export. Insects and shrimps serve as the natural host.[1]
