Iridovirus is a genus of viruses, in the family Iridoviridae.[1] Insects serve as natural hosts. There are currently only two species in this genus including the type species Invertebrate iridescent virus 6. Diseases associated with this genus include: in mosquitoes, IIV-6 usually causes covert (inapparent) infection that reduces fitness.[1][2]
Taxonomy
Group: dsDNA
- Family: Iridoviridae
- Genus: Iridovirus
Structure
Viruses in Iridovirus are enveloped, with icosahedral and Polyhedral geometries, and T=147 symmetry. The diameter is around 185 nm. Genomes are circular, around 213kb in length. The genome codes for 211 proteins.[1][2]
| Genus | Structure | Symmetry | Capsid | Genomic arrangement | Genomic segmentation |
|---|---|---|---|---|---|
| Iridovirus | Polyhedral | T=147 | Linear | Monopartite |
Life cycle
Viral replication is nucleo-cytoplasmic. Entry into the host cell is achieved by attachment of the viral proteins to host receptors, which mediates endocytosis. Replication follows the DNA strand displacement model. DNA-templated transcription is the method of transcription. Insects serve as the natural host.[2]
| Genus | Host details | Tissue tropism | Entry details | Release details | Replication site | Assembly site | Transmission |
