Salivirus
Salivirus is a genus of viruses in the order Picornavirales, in the family Picornaviridae. Humans and chimpanzees serve as natural hosts. There is only one species in this genus: Salivirus A.
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.| Genus | Structure | Symmetry | Capsid | Genomic arrangement | Genomic segmentation |
| Salivirus | Icosahedral | Pseudo T=3 | Non-enveloped | Linear | Monopartite |
Life cycle
is cytoplasmic. Entry into the host cell is achieved by attachment of the virus to host receptors, which mediates endocytosis. Replication follows the Positive-strand [RNA virus|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.| Genus | Host details | Tissue tropism | Entry details | Release details | Replication site | Assembly site | Transmission |
