Chloriridovirus is a genus of viruses, in the family Iridoviridae.[1] Diptera with aquatic larval stage, mainly mosquitoes, lepidoptera, and orthoptera insects serve as natural hosts. There are five species in this genus. Diseases associated with this genus include: yellow-green iridescence beneath the epidermis (early mosquito larval stages are most susceptible to infection). Death rates are highest in the fourth instar.[2][3] Viruses within this genus have been found to infect mosquito larvae, in which they produce various iridescent colors.[4]
Taxonomy
The genus contains the following species:[5]
- Anopheles minimus iridovirus
- Invertebrate iridescent virus 3
- Invertebrate iridescent virus 9
- Invertebrate iridescent virus 22
- Invertebrate iridescent virus 25
Structure
Viruses in the genus Chloriridovirus are enveloped, with icosahedral and polyhedral geometries, and T=189-217 symmetry. The diameter is around 180 nm. Genomes are linear, around 135kb in length. The genome codes for 126 proteins.[1][2]
| Genus | Structure | Symmetry | Capsid | Genomic arrangement | Genomic segmentation |
|---|---|---|---|---|---|
| Chloriridovirus | Polyhedral | T=189-217 | 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. Diptera with aquatic larval stage, mainly mosquitoes, lepidoptera, and orthoptera insects serve as the natural host.[1][2]
