sprivivirus sprivivirus sprivivirus is a genus of viruses in the family rhabdoviridae, order mononegavirales. fish serve as natural hosts. sprivivirus virus classification (unranked): virus realm: riboviria kingdom: orthornavirae phylum: negarnaviricota class: monjiviricetes order: mononegavirales family: rhabdoviridae genus: sprivivirus species carp sprivivirus pike fry sprivivirus taxonomy genus sprivivirus: species and their viruses genus species virus (abbreviation) sprivivirus carp sprivivirus spring viremia of carp virus (svcv) pike fry sprivivirus grass carp rhabdovirus (grcrv) pike fry rhabdovirus (pfrv) tench rhabdovirus (tenrv) structure sprivivirions are enveloped, with bullet shaped geometries. sprivivirus genomes are linear, around 11.1 kb in length. the genome codes for 5 proteins. genusstructuresymmetrycapsidgenomic arrangementgenomic segmentation sprivivirusbullet-shapedenvelopedlinear 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. genushost detailstissue tropismentry detailsrelease detailsreplication siteassembly sitetransmission sprivivirusfishnoneclathrin-mediated endocytosisbuddingcytoplasmcytoplasmtubule-guided viral movement
