Mosquito-borne diseases and control

Between March and August 1995,the prevalence of Lyme disease Borrelia in ticks and rodents in the Kuju Mountains and Sobo Mountains, the highest mountainous areas in the northern half of Kyushu, and also on the Tsushima Islands in the Korean Strait was surveyed. All 20 isolates obtained consisted of 2 Borrelia garinii (pattern C'-C on RFLP analysis) from Ixodes persulcatus from Kuju, 13 B. japonica from I. ovatus and rodents from Kuju and Sobo, 1 B. turdi from I. turdus and 4 B. tanukii from rodents from Tsushima. All these are the first official records from this region. This evidence of Borrelia is suggestive, considering their dispersal from the eastern China and Korean areas to southwestern Japan, based on biogeographical knowledge.
