Aquabirnavirus is a genus of viruses, in the family Birnaviridae.[1] Salmonid fish serve as natural hosts. There are three species in this genus. A disease associated with this genus, Infectious pancreatic necrosis (IPN) in salmonid fish, causes significant losses to the aquaculture industry. Chronic infection in adults, and acute viral disease in young salmonid fish can occur.[2][3]

Taxonomy

The genus contains the following species:[4]

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]

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]
