The Caliciviridae are a family of "small round structured" viruses, members of Class IV of the Baltimore scheme. Caliciviridae bear resemblance to enlarged picornavirus and was formerly a separate genus within the picornaviridae. [1] They are positive-sense, single-stranded RNA which is not segmented. [2]
Feline picornavirus [1] Feline calicivirus ( FCV) is a virus of the family Caliciviridae that causes disease in cats. It is one of the two important viral causes of respiratory infection in cats, the other being Felid alphaherpesvirus 1. FCV can be isolated from about 50% of cats with upper respiratory infections.

Caliciviridae. Schematic genome organization of members of genera in the family Caliciviridae. Protein VPg is covalently linked to the 5′-ends of both genomic and subgenomic RNAs and is depicted by a black circle. ORF1 encodes a polyprotein that is posttranslationally-cleaved into individual non-structural proteins.
- Description
Calicivirus genomes are positive-sense, linear, nonsegmented, single-stranded RNA. They range from 7.3 to 8.3 kilobases in length, excluding the poly (A) tail. Nonstructural proteins are located at the 5’ end, and structural proteins are located at the 3’ end. All calicivirus genomes begin with a 5’-end terminal GU sequence (VPg), which ...
Oct 1, 2019 · The family Caliciviridae includes viruses with single-stranded, positive-sense RNA genomes of 7.4–8.3 kb. The most clinically important representatives are human noroviruses, which are a leading cause of acute gastroenteritis in humans. Virions are non-enveloped with icosahedral symmetry. Members of seven genera infect mammals ( Lagovirus ...

Mar 21, 2019 · Besides noroviruses, the Caliciviridae family comprises four other accepted genera: Sapovirus, Lagovirus, Vesivirus, and Nebovirus. There are six new genera proposed: Recovirus, Valovirus, Bavovirus, Nacovirus, Minovirus, and Salovirus. All Caliciviridae have closely related genome structures, but are genetically and antigenically highly ...
