Family: Picornaviridae

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. 



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:


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


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

Species demarcation criteria

There is only a single species in the genus.
