Cyprinivirus is a genus of viruses in the order Herpesvirales, in the family Alloherpesviridae. Freshwater eels serve as natural hosts. There are currently four species in this genus, including the type species Cyprinid herpesvirus 3. Diseases associated with this genus include: hemorrhagic disease.[1][2]
Species
The genus consists of the following species:[2]
- Anguillid herpesvirus 1
- Cyprinid herpesvirus 1
- Cyprinid herpesvirus 2
- Cyprinid herpesvirus 3
- Cyprinid herpesvirus 4
Structure
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
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 |
