摘　　要：目的了解西北4省区蜱虫自然感染莱姆病螺旋体、土拉弗氏菌和Q热立克次体的情况。方法采用布旗法收集西北地区内的蜱标本进行分子生物学检测。结果文献调研显示:西北地区已报道的虫媒疾病共有15种。西北地区内共采集蜱标本2460只,涉及11个不同蜱种。共有304只蜱标本检测发现莱姆病螺旋体,75只感染土拉弗菌,200只感染Q热立克次体,3种病原体在4个调查点内均存在。共采集到西北地区内当地人群血清725份,共有183份血清存在目标抗体,进一步证实调查疾病的存在。结论证实西北四省区存在3种蜱媒疾病在,对预防控制具有重要意义。Objective To investigate the existence of Borrelia burgdorferii , Francisella tularensis and Coxiella burnetii in ticks in Northerwestern China.Methods Tick samples were collected and detected by molecular methods.Results A total of 2 460ticks of 11species were collected and tested for evidence of Borrelia burgdorferii , Francisella tularensis and Coxiella burnetii.There 304 , 75 and 200ticks harboring DNA of Borrelia burgdorferi , Francisella tularensis and Coxiella burnetii , respectively.Conclusion The in- fections of Borrelia burgdorferii , Francisella tularensis and Coxiella burnetii in ticks were proved to exist in Northerwastern China exists.
