| Aichivirus A (formerly
named Aichi virus) is the type species of the genus
Kobuvirus. This species contains five viruses (genotypes) Aichi virus 1 (found in humans), canine kobuvirus 1, murine kobuvirus 1, feline kobuvirus 1 and a kobuvirus found in sewage (see below). In a recent study a 234-amino acid (aa) fragment of a picornavirus 3Dpol was amplified from the faeces of a striped field mouse (Apodemus agrarius) (Farkas et al., 2012). Sequence comparisons (JQ408726) revealed the closest identity to murine kobuvirus 1 (93 % aa), canine kobuvirus 1 (92 % aa) and Aichi virus 1 (88 % aa) (Farkas et al., 2012). It is not clear if this virus belongs to one of the existing Aichivirus A types or if it represents a new type. The nearly complete genome sequence (6939 nt) of a possible new Aichivirus A type has recently been determined from a sewage samples from Kathmandu, Nepal (Ng et al., 2012; KoV-SewKTM; JQ898342). European roller kobuvirus 1 (Pankovics et al., 2014) is most closley related to Aichivirus A but may represent a distinct species within the genus.
