Salmovirus
Salmovirus, previously called Salmonivirus, is a genus of viruses in the order Herpesvirales, in the family Alloherpesviridae. Salmonidae serve as natural hosts. There are three species in this genus. Diseases associated with this genus include: salHV-3: epizootic epitheliotropic disease.[1][2]
The genus consists of the following three species:[2]
- Salmovirus salmonidallo1, also called Salmonid herpesvirus 1
- Salmovirus salmonidallo2, also called Salmonid herpesvirus 2
- Salmovirus salmonidallo3, also called Salmonid herpesvirus 3
Viruses in Salmovirus are enveloped, with icosahedral and spherical to pleomorphic geometries, and T=16 symmetry. The diameter is around 150-200 nm. Genomes are linear and non-segmented.[1]
| Genus | Structure | Symmetry | Capsid | Genomic arrangement | Genomic segmentation |
|---|---|---|---|---|---|
| Salmovirus | Spherical pleomorphic | T=16 | Enveloped | Linear | Monopartite |
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. Salmonidae 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 |
|---|---|---|---|---|---|---|---|
| Salmovirus | Salmonidae | None | Glycoprotiens | Budding | Nucleus | Nucleus | Passive diffusion |
