A survey on canine Hepatozoon canis infection in the western area of Yamaguchi Prefecture revealed that of the 353 dog sexamined, 28 were infected with H. canis. The infected dogs consisted of 12 hunting dogs and 16 household dogs reared in the mountainous areas of this prefecture. No significant differences were observed in the sexes and ages of the infected dogs. The ticks collected from the infected dogs were Haemaphysalis campanulata, H. longicornis, and H. flava, but no Rhipicealus sanguineus was detected. H. canis infection was also observed in 7 (26.9%) of 28 dogs infected with Babesia gibsoni. These findings suggest that H. canis infection may be widespread in this area.
