近年来,我省部份县发生了钩端螺旋体病较大规模的流行。以往调查表明,黑线姬鼠是我省钩端螺旋体病的主要传染源。为了解钩端螺旋体菌型有否变迁,我们于1988年对我省钩体病发病率较高的清镇、湄潭、遵义三县黑线姬鼠携带钩体的情况进行了调查。现将结果报告如下。对象及方法一、对象在清镇、湄潭、遵义三县的稻田中共捕获成年黑线姬鼠383只;其中清镇121只,湄潭132只,遵义130只。二、方法所有黑线姬鼠均取小块肾组织 In recent years, some counties in our province occurred a large-scale epidemic of leptospirosis. Past investigations show that Apodemus agrarius is the main source of infection of leptospirosis in our province. In order to understand whether the leptospiral bacteria have changed, we conducted a survey in 1988 on the incidence of hooked bodies of Apodemus agrarius in Qingzhen, Meitan and Zunyi provinces, which had a high incidence of leptospirosis in our province. The results reported below. Subjects and Methods I. Object In the Qingzhen, Meitan and Zunyi paddy fields, 383 adult Apodemus agrarius were captured; 121 were Qingzhen, 132 were Meitan and 130 were Zunyi. Second, methods All the black line Apodemus were small pieces of kidney tissue
