四川省1993-2001年钩端螺旋体病传染源监测分析

Analysis of Leptospirosis Infection Source Surveillence in Sichuan Province from 1993 to 2001

目的 调查研究四川省 1993 -2 0 0 1年钩端螺旋体 (简称钩体 )病传染源情况 ,为防治该病提供科学依据。方法 按全国钩体病监测方案全省选择 10个监测点 ,进行钩体病主要传染源调查。结果 黑线姬鼠带菌率占第 1位 ,主要携带黄疸出血群钩体 ,首次从牛尿中检出七日热群钩体 结论 鼠密度、鼠带菌率、带菌鼠密度分别与钩体发病率呈正相关。黑线姬鼠是四川省稻田型钩体主要传染源。耕牛作为七日热群钩体宿主和重要传染源应继续调查。

Objective To survey the situation of leptospirosis infection source in Sichuar province from 1993 to 2001 in order to provide a basis for scientific research Methods A total of 10 surveillance sites were selected in the whole province,according to national surveillance scheme for leptospirosis,to conduct the survey on main infection sources of leptospirosis Results The carrier rate of Apodemus agrarius was the highest one Hebdomadis serogroup Loptospira first were isolated from urine of buffalo in 2000 Conclusions The density and carrier rate of rat are positively correlated with the incidence rate of Leptosprosis Apodemus agraius is the principal infection source of Rice Field patten Leptospirasis in Sichuan province It should be continued to study that baffalo is the important infection source and the host animal of Hedomadis Leptospirosis in Sichuan province
