Taxonomy
The genus contains the following species:
* ''
Blotched snakehead virus''
* ''
Lates calcarifer birnavirus''
Structure
Viruses in ''Blosnavirus'' are non-enveloped, with icosahedral and Single-shelled geometries, and T=13 symmetry. The diameter is around 70 nm. Genomes are linear and have 2 segments, around 2.7-3.4kb in length. The genome codes for 6 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. Blotched snakehead fish serve as the natural host.
