The genus is distinguished on the basis of genetic characters.
No details are available on the morphology of virions.
Genome: (Zhang et al., 2017) 8,003–8,100 nt (5′-UTR: 1232–1345 nt; ORF: 6,573–6,654 nt; 3′-UTR: 97–117 nt). The location of cre has not been identified.
Genome organization and replication
The deduced polyprotein is of 2,191 amino acids. There is no L protein. The 2A protein has an NPG↓P motif.
No virus has been isolated. Viral RNA was detected in faecal specimens of wild (one sick, one healthy) and captive (healthy) giant pandas (Ailuropoda melanoleuca).
Derivation of names
Ailurivirus: from Ailuropoda melanoleuca (host).
Species demarcation criteria
