The virus genus Hepandensovirus belongs to the Densovirinae subfamily[1] of the family Parvoviridae.[2][3]. Insects and shrimps serve as natural hosts. Infection leads to mortality in the early larval and postlarval stages of the shrimp.[4][5] There is currently only one species in this genus: the type species Decapod hepandensovirus 1.

- Sub-Family: Densovirinae
- Genus: Hepandensovirus
- Decapod hepandensovirus 1
Structure
Viruses in genus Hepandensovirus are non-enveloped, with T=1 icosahedral symmetry and round geometries. The diameter is around 21-22 nm. Genomes are linear, around 6kb in length.[4][3]
| Genus | Structure | Symmetry | Capsid | Genomic arrangement | Genomic segmentation |
|---|---|---|---|---|---|
| Hepandensovirus | Icosahedral | T=1 | Non-enveloped | Linear | Segmented |
Life cycle
Viral replication is nuclear. Entry into the host cell is achieved by attachment to host receptors, which mediate 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.[4][3]
| Genus | Host details | Tissue tropism | Entry details | Release details | Replication site | Assembly site | Transmission |
