No details are available on the morphology of virions. 

Nucleic acid

Genome (R. Tokarz and WI Lipkin, unpublished): 7,018 nt (5′-UTR: >248 nt; ORF: 6,669 nt; 3′-UTR: 101 nt). The location of the cre has not been identified. 

Genome organization and replication

Genome layout:

VPg+5′-UTR^IRES-[1A-1B-1C-1D-2A^npgp/2B-2C/3A-3B-3C-3D]-3′-UTR-poly(A)

The deduced polyprotein is of 2,223 amino acids. There is no L protein. 

Biology

No virus has been isolated. Viral RNA was detected in samples of cattle (Bos taurus). 

Derivation of names

Bopivirus: from bovine picornavirus

Species demarcation criteria
