salivirus salivirus salivirus is a genus of viruses in the order picornavirales, in the family picornaviridae. human and chimpanzee serve as natural hosts. there is only one species in this genus: salivirus a. diseases associated with this genus include: probably gastroenteritis. salivirus virus classification (unranked): virus realm: riboviria kingdom: orthornavirae phylum: pisuviricota class: pisoniviricetes order: picornavirales family: picornaviridae genus: salivirus structure viruses in salivirus are non-enveloped, with icosahedral and spherical geometries, and t=pseudo3 symmetry. the diameter is around 30 nm. genomes are linear and non-segmented, around 6-8kb in length. genusstructuresymmetrycapsidgenomic arrangementgenomic segmentation salivirusicosahedralpseudo t=3non-envelopedlinearmonopartite life cycle viral replication is cytoplasmic. entry into the host cell is achieved by attachment of the virus to host receptors, which mediates endocytosis. replication follows the positive stranded rna virus replication model. positive stranded rna virus transcription is the method of transcription. the virus exits the host cell by lysis, and viroporins. human and chimpanzee serve as the natural host. genushost detailstissue tropismentry detailsrelease detailsreplication siteassembly sitetransmission salivirushuman, chimpanzeenonecell receptor endocytosislysiscytoplasmcytoplasmunknown pathogenesis the virus has been isolated from diarrheal specimens. but the role of the virus in the pathogenesis of gastroenteritis was ambiguous. meta-analysis showed that the virus is not associated with gastroenteritis.
