The genus is distinguished on the basis of genetic characters.
No details are available on the morphology of virions.
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
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
