Omegatetravirus is a genus of viruses, in the family Alphatetraviridae . Moths and butterflies serve as natural hosts. There are three species in this genus. Infection outcome varies from unapparent to lethal. [1] [2]
The following species are assigned to the genus: [2]
Viruses in Omegatetravirus are non-enveloped, with icosahedral geometries, and T=4 symmetry. The diameter is around 40 nm. Genomes are linear and bipartite, around 2.5kb in length. [1]
| Genus | Structure | Symmetry | Capsid | Genomic arrangement | Genomic segmentation |
|---|---|---|---|---|---|
| Omegatetravirus | Icosahedral | T=4 | Non-enveloped | Linear | Segmented |
Viral replication is cytoplasmic. Entry into the host cell is achieved by penetration into the host cell. Replication follows the positive stranded RNA virus replication model. Positive stranded RNA virus transcription is the method of transcription. Translation takes place by leaky scanning. Moths and butterflies serve as the natural host. Transmission routes are oral. [1]
| Genus | Host details | Tissue tropism | Entry details | Release details | Replication site | Assembly site | Transmission |
|---|---|---|---|---|---|---|---|
| Omegatetravirus | Moths; butterflies | Midgut | Cell receptor endocytosis | Budding | Cytoplasm | Cytoplasm | Oral |
