Epidemiological survey for canine tick-borne diseases in Japan

巴贝斯虫病和肝虫病是蜱传疾病，被认为是犬科动物实践中的重要传染病。对这些病原体进行了分子流行病学调查。吉氏巴贝斯虫感染的狗主要发现于日本西部地区的狗。然而，秋田县的一只狗也感染了巴贝虫。分子分析显示，这只狗体内的巴贝虫与反刍动物巴贝虫 B.odocoilei 密切相关。这将是本研究的一个重要发现。在岩手县、茨城县、石川县、福井县、静冈县、滋贺县、和歌山县、岛根县、广岛县、山口县、香川县、长崎县和熊本县的狗身上发现了感染犬肝虫的狗。据了解，犬嗜血杆菌广泛分布于日本东北、关东、北陆、中国、四国和九州地区。此外，据透露，大多数日本野猫都感染了H. felis。

Babesiosis and hepatozoonosis are tick-borne diseases and are recognized as an important infectious disease in canine peractice. Molecular epidemiological survey for these pathogens was conducted. Babesia gibsoni-infected dogs were mainly found in dogs from western area of Japan. However, one dog from Akita prefecture was also positive for Babesia infection. Molecular analysis revealed that Babesia in this dog is closely related to a ruminant Babesia, B.odocoilei. This will be an important finding in this study. Hepatozoon canis-infected dogs were found in dogs from Iwate, Ibaraki, Ishikawa, Fukui, Shizuoka, Shiga, Wakayama, Shimane, Hiroshima, Yamaguchi, Kagawa, Nagasaki and Kumamoto prefectures. It was revealed that H. canis is widely distributing in Japan including Tohoku, Kanto, Hokuriku, Chugoku, Shikoku and Kyushu areas. In addition, it was revealed that most of Japanese wildcats were infected with H. felis.
