The genus is distinguished on the basis of genetic characters.
No details are available on the morphology of virions.
Genome (Lau et al., 2012): c. 7,391 nt (5′-UTR: >299 nt; ORF: 7,011 nt; 3′-UTR: 81 nt). The location of the cre has not been identified.
Genome organization and replication
The deduced polyprotein is of 2,337 amino acids. There is an L protein with unknown function. The 2A protein has been proposed to be a chymotrypsin-like protease.
No virus has been isolated. Viral RNA was detected in faecal samples of domestic cats. Two genetic types have been identified by means of phylogenetic analysis.
Derivation of names
Felipivirus: derived from feles (Latin, cat) and picornavirus
Species demarcation criteria
There is only a single species in the genus.
