Genus: Felipivirus

Genus: Felipivirus

Distinguishing features

The genus is distinguished on the basis of genetic characters.

Virion

Morphology

No details are available on the morphology of virions.

Nucleic acid

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

Genome layout:

VPg+5′-UTRIRES-[L-1A-1B-1C-1D/2Apro-2B-2C/3A-3B-3C-3D]-3′-UTR-poly(A)

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.

Biology

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
