Genus: Ailurivirus


Genus: Ailurivirus

Distinguishing features

The genus is distinguished on the basis of genetic characters.

Virion

Morphology

No details are available on the morphology of the virions.

Nucleic acid

Genome: (Zhang et al., 2017) 8003-8100 nt (5'UTR: 1232-1345 nt; ORF: 6573-6654 nt; 3'UTR: 97-117 nt). The location of cre has not been identified.

Genome organization and replication

Genome layout:

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

The deduced polyprotein is of 2,191 amino acids. There is no L protein. 2A protein has a NPG¯P motif.

Antigenicity

See discussion under family description.

Biology

Viral RNA was detected in faecal specimens of wild (one sick, one healthy) and captive (healthy) giant pandas (Ailuropoda melanoleuca).
