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]
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]
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]
