  Canine kobuvirus 1 (CaKV-1) is a new virus which can be classified within the genus Kobuvirus (Li et al., 2011; Carmona-Vicente et al., 2013). CaKV-1 is most closely related to murine kobuvirus 1 and Aichi virus 1, and probably represents a novel Aichivirus A genotype.

A second genome sequence of a canine kobuvirus has also recently been published (Kapoor et al., 2011). These two viruses are closely related, e.g. 6.7% nt / 6.0% aa difference in VP1.

Recently, Yamashita et al. (2011) reported the partial genome sequence (~5kb) of an Aichi-like virus (Y12/04) from wastewater in Japan. This sequence was closely related to the canine kobuviruses described above.

The partial 3Dpol sequences of a feline kobuvirus has been detected in cats in South Korea. These sequences are related to canine kobuvirus 1 by 87% nt id.

VP1 and partial 3D sequences of kobuvirus of red foxes (Vulpes vulpes) in Italy and Spain are closely related to canine kobuvirus 1 (Di Martino et al., unpublished; Bodewes et al., 2014).

Recently, canine kobuviruses have been found in domestic or wild carnivores in Africa (Olarte-Castillo et al., 2015).
