Salivirus

Salivirus is a genus of viruses in the order Picornavirales, in the family Picornaviridae. Human and chimpanzee serve as natural hosts. There is currently only one species in this genus: the type species Salivirus A. Diseases associated with this genus include: probably gastroenteritis.[1][2]

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.[1]

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.[1]
