目的了解凤台县自然人群及宿主动物钩体病感染情况,为预防控制钩体病提供依据。方法采用显微凝集实验检测人血清,滴度?1:100(++)为隐性感染;采用柯索夫培养基,孵育分离宿主动物肾脏钩体并分型。结果2005~2007年共检测人血清383份,其中阳性14人,隐性感染率为3.66%。捕获宿主动物401只(主要是鼠类),带菌40只,带菌率为9.98%,均为黄疸出血型。结论凤台县有钩体病潜在流行的可能,必须做好防治工作。
Objective To understand the prevalence of leptospirosis in the natural population and host animals in Fengtai County and provide evidence for the prevention and control of leptospirosis. Methods The microscopic agglutination test was used to detect human serum. The titer was 1: 100 (++), which was recessive infection. Results A total of 383 human serum samples were obtained from 2005 to 2007, of which 14 were positive and the latent infection rate was 3.66%. 401 host animals (mainly rodents) were captured and 40 were inoculated, with a carriage rate of 9.98%. All of them were jaundiced bleeding. Conclusion There is a potential epidemic of leptospirosis in Fengtai County and prevention and treatment must be well done.
