目的了解近年山东省沂源县西部地区农村人口恙虫病东方体、地方性斑疹伤寒立克次体和斑点热立克次体的感染情况,为自然疫源性疾病的预防和控制提供依据。方法 2011年从山东省沂源县西部乡镇的农村人口中随机收集192份血清,采用间接免疫荧光法检测血清中恙虫病东方体、地方性斑疹伤寒立克次体和斑点热立克次体抗体。结果恙虫病东方体、地方性斑疹伤寒立克次体和斑点热立克次体抗体血清阳性率分别为56.77%(109/192)、79.69%(153/192)和69.79%(134/192)。结论山东省沂源县西部农村人口中恙虫病东方体、地方性斑疹伤寒立克次体和斑点热立克次体的感染率较高。
OBJECTIVE To understand the infection of Rickettsia tsutsugamushi, Rickettsia rickettsi and Rickettsia rickettsi in rural areas of western Yiyuan County in Shandong Province in recent years, and to provide basis for the prevention and control of natural foci. Methods A total of 192 serum samples were collected from the rural population in the western towns of Yiyuan County in Shandong Province in 2011.
