Aquabirnavirus is a genus of viruses, in the family Birnaviridae.[1] Salmonid fish serve as natural hosts. There are currently three species in this genus including the type species Infectious pancreatic necrosis virus. Diseases associated with this genus include: IPNV:infectious pancreatic necrosis in salmonid fish, causes significant losses to the aquaculture industry. chronic infection in adult, and acute viral disease in young salmonid fish.[2][3]
Taxonomy
Group: dsRNA
Order: Unassigned
- Family: Birnaviridae
- Genus: Aquabirnavirus
Structure
Viruses in Aquabirnavirus are non-enveloped, with icosahedral and Single-shelled geometries, and T=13 symmetry. The diameter is around 70 nm. Genomes are linear and segmented, around 2.7-3kb in length. The genome codes for 5 proteins.[2][3]
| Genus | Structure | Symmetry | Capsid | Genomic arrangement | Genomic segmentation |
|---|---|---|---|---|---|
| Aquabirnavirus | Icosahedral | T=13 | Non-enveloped | Linear | Segmented |
Life cycle
Viral replication is cytoplasmic. Entry into the host cell is achieved by penetration into the host cell. Replication follows the double-stranded RNA virus replication model. Double-stranded rna virus transcription is the method of transcription. Salmonid fish serve as the natural host. Transmission routes are contact.[2][3]
| Genus | Host details | Tissue tropism | Entry details | Release details | Replication site | Assembly site | Transmission |
|---|---|---|---|---|---|---|---|
| Aquabirnavirus | Salmonid fish | None | Cell receptor endocytosis | Budding | Cytoplasm | Cytoplasm | Contact |
