Blosnavirus

Blosnavirus is a genus of viruses, in the family "Birnaviridae". Blotched snakehead fish serve as natural hosts. There are currently two species in this genus including the type species "Blotched snakehead virus".
Taxonomy.
Group: dsRNA
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.
