目的：调查宁夏六盘山及周边地区莱姆病自然疫源地状况。方法：分别采用间接免疫荧光法（IFA）、ELISA法，检测人、畜血清莱姆病抗体．采集蜱类进行病原分离。结果：检测757人，抗莱姆病螺旋体IgG抗体阳性（≥1：128）24人，自然感染率3．17％，并查出典型莱姆病病例；黄牛、绵羊、山羊抗莱姆病抗体阳性水分别为23．88％（16／67）、15．82％（25／158）、20．31％（13／64）。共采集硬蜱4属5种141只，其中1属4种为宁夏首次记录；全沟硬蜱带菌率为50．0％（5／10），从80只全沟硬蜱分离出3株莱姆病疏螺旋体。结论：首次证实宁夏六盘山地两侧及前山丘陵地区、盐池县存在莱姆病自然疫源地。
Objective: To investigate the natural epidemic situation of Lyme disease in Liupan Mountain and the surrounding areas in Ningxia. Methods: Indirect immunofluorescence (IFA) and ELISA were used to detect human and animal serum Lyme disease antibody. Collection of ticks for pathogen isolation. Results: A total of 757 people were tested for anti-Lyme disease spirochete IgG antibody (≥1: 128), 24 patients were infected with natural infection rate of 3.17%, and typical cases of Lyme disease were detected. Positive water were 23.88% (16/67), 15.82% (25/158) and 20.31% (13/64), respectively. A total of 141 species belonging to 4 genera and 5 species of Ixodes were collected, of which 4 species belonging to 4 genera and 1 genus were recorded for the first time in Ningxia. The incidence of Ixodida was 50.0% (5/10) Mycosis Borrelia. Conclusion: It is the first time to confirm that there are natural foci of Lyme disease in Yanchi County on both sides of Liupan Mountain and the hilly area of Ningxia.
