Cyvirus, also known as Cyprinivirus is a genus of viruses in the order Herpesvirales, in the family Alloherpesviridae. Freshwater eels serve as natural hosts. There are four species in this genus. Diseases associated with this genus include: hemorrhagic disease.[1][2]
Species
[edit]The genus consists of the following four species:[2]
Structure
[edit]Viruses in Cyprinivirus are enveloped, with icosahedral and spherical to pleomorphic geometries, and T=16 symmetry. The diameter is around 200 nm. Genomes are linear and non-segmented, around 10kb in length. The genome codes for 136 proteins.[1]
| Genus | Structure | Symmetry | Capsid | Genomic arrangement | Genomic segmentation |
|---|---|---|---|---|---|
| Cyprinivirus | Spherical pleomorphic | T=16 | Enveloped | Linear | Monopartite |
Life cycle
[edit]Viral replication is nuclear, and is lysogenic. Entry into the host cell is achieved by attachment of the viral glycoproteins to host receptors, which mediates endocytosis. DNA-templated transcription is the method of transcription. Freshwater eel serve as the natural host. Transmission routes are passive diffusion.[1]
| Genus | Host details | Tissue tropism | Entry details | Release details | Replication site | Assembly site | Transmission |
|---|---|---|---|---|---|---|---|
| Cyprinivirus | Fresh water eel | None | Glycoprotiens | Budding | Cytoplasm | Cytoplasm | Passive diffusion |
