摘　　要：目的:了解一起食源性疾病暴发的原因。方法:采用流行病学调查及实验室分离培养确认致病原。结果:在3份病人肛试子和3份末梢水中检出有致病性大肠埃希氏菌,未检出其它致病菌。一日三餐均饮用该水的教师和家属发病率为66.67%,而在校一日只进一餐的学生发病率为26.23%,前者显著高于后者(χ2=52.63,P<0.01)。当地场镇居民只用不饮此水未见发病。结论:通过流行病学调查和实验室病原学检查,证实本起疫情系一起致病性大肠埃希氏菌引起的食源性疾病暴发疫情。Objective：To investigate and analyze the epidemiological characters of an outbreak of food poisoning in a school.
