Genus: Ampivirus

Genus: Ampivirus

Distinguishing features

The genus is distinguished on the basis of genetic characters. The known ampiviruses have rather large protease and polymerase proteins compared to those of other picornaviruses.

Virion

Morphology

No details are available on the morphology of virions.

Nucleic acid

Genome (Reuter et al., 2015): 9,246 nt (5′-UTR: 970 nt; ORF: 8,142 nt; 3′-UTR: 134 nt). The location of the cre has not been identified. 

Genome organization and replication

Genome layout:

VPg+5′-UTRIRES-[1AB-1C-1D/2A-2B-2C/3A-3B-3C-3D]-3′-UTR-poly(A)

The deduced polyprotein is of 2,713 amino acids. There is no L protein. The function of 2A is unknown. 

Biology

No virus has been isolated. Viral RNA was detected in faeces of apparently healthy common newts (Lissotriton vulgaris).

Derivation of names

Ampivirus: from amphibian picornavirus
