Epidemiological survey for canine tick-borne diseases in Japan

巴贝斯虫病和肝虫病是蜱媒传染病，是犬生产中的重要传染病。对这些病原体进行分子流行病学调查。吉氏巴氏杆菌感染犬主要见于日本西部地区的犬。然而，来自秋田县的一只狗也对巴氏杆菌感染呈阳性。分子分析表明，Bababelae在这只狗是密切相关的反刍动物Bababelae，B. odocoilei。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、长崎县和熊本县的犬中发现了犬肝体感染犬。结果表明，H.犬的分布范围很广，包括日本东北、关东、北陆、中国、四国和九州地区。此外，日本野猫感染H.猫

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.
