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.

Species

The genus consists of the following three species:Salmovirus salmonidallo1, also called Salmonid herpesvirus 1Salmovirus salmonidallo2, also called Salmonid herpesvirus 2Salmovirus salmonidallo3, also called ''Salmonid herpesvirus 3''

Structure

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.

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. Salmonidae serve as the natural host. Transmission routes are passive diffusion.
