- Blotched snakehead virus
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.[1]
| Genus | Structure | Symmetry | Capsid | Genomic arrangement | Genomic segmentation |
|---|---|---|---|---|---|
| Blosnavirus | 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. Blotched snakehead fish serve as the natural host.[1]
