Entomobirnavirus is a genus of viruses in the family Birnaviridae.[1] Its natural host is the fly Drosophila melanogaster. There are two species in this genus.[2][3]
Taxonomy
The genus contains the following species:[4]
- Drosophila X virus
- Mosquito X virus
Structure
Viruses in the genus Entomobirnavirus 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 15.3.2-3.5kb in length. The genome codes for 5 proteins.[2][3]
| Genus | Structure | Symmetry | Capsid | Genomic arrangement | Genomic segmentation |
|---|---|---|---|---|---|
| Entomobirnavirus | 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. Drosophila melanogaster serve as the natural host.[2][3]
