Genus: Ampivirus

Genus: Ampivirus

Distinguishing features

Ampiviruses have rather large protease and polymerase proteins compared to those of other picornaviruses.



No virus has been isolated.

Nucleic acid

Length of 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 has a length of 2,713 amino acids. There is no L protein. The function of 2A is unknown.


See discussion under family description.


Viral RNA was detected in faeces of apparently healthy common newts (Lissotriton vulgaris).
