Family: Picornaviridae
Genus: Ludopivirus
Distinguishing features
The genus is distinguished on the basis of genetic characters.
Virion
Morphology
No details are available on the morphology of virions.
Nucleic acid
Genome (Boros et al., 2018): c. 8,051 nt (5′-UTR: 529 nt; ORF: 7,257 nt; 3′-UTR: 265 nt). The location of the cre has not been identified.
Genome organization and replication
Genome layout:
VPg+5′-UTRIRES-[L-1AB-1C-1D/2AH-box/NC-2B-2C/3A-3B-3C-3D]-3′-UTR-poly(A)
The deduced polyprotein is of 2,419 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.
Biology
No virus has been isolated. Viral RNA was detected in a cloacal sample of greater white-fronted geese (Anser albifrons).
Derivation of names
Ludopivirus: derived from Hungarian lúd (goose) and picornavirus
Species demarcation criteria
There is only a single species in the genus.
