||Aichivirus A (formerly
named Aichi virus) is the type species of the genus
This species contains three viruses (types) Aichi virus 1
(found in humans), canine kobuvirus 1 and
murine kobuvirus 1.
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 three Aichivirus A types or if it represents a new
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).
