摘　　要：目的研究怀远县人群钩端螺旋体感染及宿主动物带菌情况,为控制该病提供依据。方法采用血清学、病原学、流行病学方法对钩体病进行监测。结果自然人群感染率流行季节高于非流行季节(9.00∶0.96),均为黄疸出血群。宿主动物鼠种构成较以往发生明显改变,黑线姬鼠占84.02%,鼠密度秋季高于春季(10.54∶8.63),鼠带菌率秋季高于春季(24.53∶4.54),感染菌群与人一致。结论怀远县钩体病流行菌群由1970年代波摩那群更迭为黄疸出血群[1]。主要带菌宿主动物由猪改变为黑线姬鼠,鼠感染菌群更迭与人感染情况吻合。今后应加强宿主动物调查和人群钩体病疫情调查研究,掌握流行动态,及时采用有效的防治对策,防止黄疸出血群钩体病暴发流行。Objective To investigate leptospirosis infection in natural population and in the host animal so as to provide basis for leptospirosis control and prevention. Methods Serological, etiological and epidemiological methods were used in the surveillance. Results The inapprant infection rate in epidemic season was higher than that in non - epidemic season （9.00：0.96）, and Leterohe morrhagiae group accounted for 100%. The predominant host animal had changed from swine to Apodemus agrarius （ accounted 84.02% ）. In spring, infection rate of host animal was higher than autumn, which was in concoidance with the population infection. Conclusion The epidemic group had changed from Promonia in 1970s to Lcteroho morrhagiae, which was in concord with population infection. The host animal had changed from swine to Apodemus agraflus. Group- alternative indicated that investigations and methods should be enforced in order to control the outbreak of Leptospirosis.
