Family: Picornaviridae

Genus: Livupivirus


Distinguishing features

The genus is distinguished on the basis of genetic characters. 



No details are available on the morphology of virions. 

Nucleic acid

Genome (Pankovics et al., 2017b): c. 7,770 nt (5′–UTR: 610 nt; ORF: 7,062 nt; 3′–UTR: 96 nt). 5′–UTR contains a type IV IRES. The location of the cre has not been identified. 

Genome organization and replication

Genome layout:

VPg+5′-UTRIRES-IV- [L-1AB-1C-1D/2AH-box/NC-2B-2C/3A-3B-3C-3D]-3′-UTR

The deduced polyprotein is of 2,354 aa. 1AB remains uncleaved. The 2A protein has an H-box/NC motif. 


No virus has been isolated. Viral RNA was detected in faecal specimens of apparently healthy smooth newts (Lissotriton vulgaris). 

Derivation of names

Livupivirus: derived from Lissotriton vulgaris (host) picornavirus

Species demarcation criteria

There is only a single species in the genus.
