Genus: Livupivirus

Genus: Livupivirus

Distinguishing features

The genus is distinguished on the basis of genetic characters.



No details are available on the morphology of the virions. 

Nucleic acid

Genome (Pankovics et al., 2017): c. 7770 nt (5'–UTR: 610 nt; ORF: 7062 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. 2A protein has a H-box/NC motif.


Viral RNA was detected in faecal specimens of apparently healthy smooth newts (Lissotriton vulgaris).

Derivation of names

Livupi-: Lissotriton vulgaris (host) picornavirus
