致病性大肠菌(EPEC),产毒性大肠菌(ETEC)和侵袭性大肠菌(EIEC)等三群病原性大肠菌是引起急性感染性腹泻的主要病原菌。为了探索外环境污染病原性大肠菌及其与感染性腹泻的关系,我们于1985年5月至1990年5月在南宁市的外环境进行了连续5年的病原学监测,同时在广西融水和乐业两县采集饮用水、苍蝇等标本进行检查,现将结果报告如下。材料与方法1.标本的采集:在南宁市每季度定点采集水源标本,在农贸集市上不定点采集淡水
Three groups of pathogenic coliforms such as pathogenic Escherichia coli (ECEC), enterotoxigenic Escherichia coli (ETEC) and invasive coliforms (EIEC) are the main pathogens causing acute infectious diarrhea. In order to explore the relationship between pathogenic Escherichia coli and infectious diarrhea outside the environment, we conducted etiological surveillance for 5 consecutive years from May 1985 to May 1990 in the outer environment of Nanning City. At the same time, Le and two counties to collect drinking water, flies and other specimens for inspection, the results are reported as follows. Materials and methods 1. Collection of specimens: In Nanning City quarterly collection of water samples collected at a fixed point in the farmers market to collect fresh water
