Family: Picornaviridae

Genus: Shanbavirus

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 (Reuter et al., 2015, Wu et al., 2016): 7,264 nt (5′-UTR: >478 nt; ORF: 6,429 nt; 3′-UTR: 357 nt). The location of the cre has not been identified. 

Genome organization and replication

Genome layout:

VPg+5′-UTR^IRES-[1AB-1C-1D-2A1^npgp/2A2^H-box/NC-2B-2C/3A-3B-3C-3D]-3′-UTR-poly(A)

The deduced polyprotein is of c. 2,143 amino acids. There is no L protein. The 1AB protein remains uncleaved. The 2A1 protein has an NPG↓P motif; the 2A2 protein has an H-box/NC motif. 

Biology

No virus has been isolated. Viral RNA was detected in tissue samples of Miniopterus fuliginosus bats in China. 

Derivation of names

Shanbavirus: from Shanxi bat picornavirus (Shanxi Province in China where sample was collected)

Species demarcation criteria

There is only a single species in the genus.
