The genus is distinguished on the basis of genetic characters.
No details are available on the morphology of the virions.
Genome (Boros et al., 2013): c. 7092–7429 nt (5′-UTR: >393–532 nt; ORF: 6,657–6,747 nt; 3′-UTR: 25–180 nt). 5′-UTR contains a type IV-B IRES. The 3′-UTR of members of the species Kunsagivirus A are the shortest of picornaviruses, at 25 nt. The location of the cre has not been identified.
The deduced polyprotein is of 2,248 amino acids. There is no L protein. 1AB remains uncleaved. 2A1 is a short foot-and-mouth disease virus (FMDV)-like polypeptide (NPG¯P), bakunsaviruses have three FMDV-like 2A proteins, another 2A protein has unknown function.
See discussion under family description.
Viral RNA of an isolate of Kunsagivirus A was detected in faeces of an apparently healthy European roller (Coracias garrulus), of Kunsagivirus B in faeces of the fruit bat Eidolon helvum, and of Kunsagivirus C in wild baboons (Papio cynocephalus).
Members of a species of the genus Kunsagivirus share a common genome organization.
The divergence (number of differences per site between sequences) between members of different Kunsagivirus species is for 0.51 for P1 and 0.52 for 3CD
Kunsagi-: from the name of part of the Great Hungarian Plain – "Kunság" – where the first samples were collected
