摘要
应用免疫荧光方法(IFA)对湖北省东北部地区的英山县进行了莱姆病的流行病学调查。结果,人群总感染率为8.8%(24/272),其中林区居民及非林区居民感染率分别为12.8%(22/172)及2.0%(2/100),两者差异有高度显著性(P=0.005);共采集蜱484只,其中微小牛蜱308只,豪猪血蜱136只,二棘血蜱40只。经检测,不同蜱种带菌率为0~15%。本调查证实湖北省东北部地区存在莱姆病,人群感染菜姆病与环境性蜱暴露有密切关系。
An epidemiological investigation of Lyme Disease was carried out with immunofluorescent assay(IFA) in Yingshan County,Htibei Province from l992.9~1993.10.Out of the 272 serum samples,24(8.8%)were positive for IgG antibodies against Borrelia buegdor feri B_(31) The prevalances were 12.8%(22/172)in the forest population and 2.0%(2/100) in nonforest ones respectively.There were significant differences between forest and non-forest residents,but there were no significant differences in t sexes and age groups.All the 484 ticks included 308 B. microplus and 136 H. hystricis and 40 H. bispinoses were obtained and Borrelia was identified in 0~15%of the ticks gut preparation. The results confirmed the existence of Lyme disease in Hubei Province and most of the infections could be attributed to the exposure to ticks in the environment.
