Family: Picornaviridae

Genus: Pemapivirus


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 (Shi et al., 2018): c. 9,196 nt (5′-UTR: 668 nt; ORF: 8,235 nt; 3′-UTR: 293 nt). The location of the cre has not been identified. 

Genome organization and replication

Genome layout:


The deduced polyprotein is of 2,745 amino acids. There is an L protein with unknown function. The 1AB protein remains uncleaved. The 2A protein has an H-box/NC sequence motif. 


No virus has been isolated. Viral RNA was detected in organ pools (gut, liver, lungs) of Chinese softshell turtles (Pelodiscus sinensis) and Chinese broad-headed pond turtles (Mauremys megalocephala). 

Derivation of names

Pemapivirus: derived from Pelodiscus sinensis and Mauremys megalocephala (hosts) and picornavirus
