目的　探讨安徽省不同地区钩端螺旋体病的特征。方法　采用病原学和血清学对自然人群感染情况及主要宿主感染情况及带菌率、菌群分布进行调查。结果　不同地理区划人群感染率及流行菌群均不相同 ,皖南山区出现菌型更迭现象。结论　淮河长江流域自然人群隐性感染率下降 ,宿主动物均有带菌 ,疫区仍然存在 ;皖南山区与七十年代持平 ,并发现新的菌型 ,是九十年代重点疫区 ,应采取相应防治措施

Investigation of Leptospirosis Infection of Human and Main Reservoirs in different Geographic Landscape of Anhui Province

Objective The purpose of this article is to discuss the characteristic of Leptospirosis in different areas of Anhui province. Methods We investigated the infection of cardinal host animals and the distribution of flora by etiology separation and serological detection. Results The infection rate of people and epidemical flora were different in several regions. L.interrogans alternated apparently in Wannan Mountainous area. Conclusions Inapparent infection rate of people along Huai river and Yangtse River went down. The host animals were infected and the epidemic area was still existed. The inapparent infection rate of people was equal to that in the seventies and we found new flora in Wannan mountainous area. It suggested that we should take corresponding preventive strategy.
