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 (Naoi et al., 2016): 7,062 nt (5′–UTR: 754 nt; ORF: 6,273 nt; 3′–UTR: 125 nt). The location of the cre has not been identified.
Genome organization and replication
Genome layout:
VPg+5′-UTRIRES-[L-1A-1B-1C-1D/2A-2B-2C/3A-3B-3C-3D]-3′-UTR
The deduced polyprotein is of 2,091 aa. The function of the L and 2A proteins is unclear.
Biology
No virus has been isolated. Viral RNA was detected in a faecal specimen of a healthy, 2-month old piglet.
Derivation of names
Tottorivirus: place name, refers to the Tottori prefecture, Japan, where the faecal sample was collected.
Species demarcation criteria
There is only a single species in the genus.
