Species

The genus consists of the following four species:[2]

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]

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]
