Genus: Shanbavirus

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 (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′-UTRIRES-[1AB-1C-1D-2A1npgp/2A2H-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 a NPG¯P motif, 2A2 protein has a H-box/NC motif.

Antigenicity

See discussion under family description.

Biology

Viral RNA was detected in tissue samples of Miniopterus fuliginosus bats in China.
