Aquabirnavirus

Aquabirnavirus is a genus of viruses, in the family "Birnaviridae". 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.
Taxonomy.
Group: dsRNA
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.
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.
