Sprivivirus is a genus of viruses in the order Mononegavirales, in the family Rhabdoviridae. Fish serve as natural hosts. There are currently only two species in this genus, including the type species Spring viraemia of carp virus.[1][2]

Structure
Viruses in Sprivivirus are enveloped, with bullet shaped geometries. Genomes are linear, around 11.1kb in length. The genome codes for 5 proteins.[1]

Life Cycle
Viral replication is cytoplasmic. Entry into the host cell is achieved by attachment of the viral G glycoproteins to host receptors, which mediates clathrin-mediated endocytosis. Replication follows the negative stranded RNA virus replication model. Negative stranded RNA virus transcription, using polymerase stuttering is the method of transcription. The virus exits the host cell by budding, and tubule-guided viral movement. Fish serve as the natural host.[1]
| Genus | Host Details | Tissue Tropism | Entry Details | Release Details | Replication Site | Assembly Site | Transmission |
|---|---|---|---|---|---|---|---|
| Sprivivirus | Fish | None | Clathrin-mediated endocytosis | Budding | Cytoplasm | Cytoplasm | Tubule-guided viral movement |
