摘　　要：目的了解医院肠道门诊致病菌腹泻病例的流行病学特征及其流行菌株,为感染性腹泻防治提供依据。方法在一、二级医院肠道门诊对因腹泻就诊,经病原学监测结果为肠道致病菌感染的病例,进行临床症状、可疑食物史调查,并对病原学检测结果进行分析。结果 337例患者就诊前的平均腹泻次数为5.87次;所有患者均有不同程度的大便性状改变,稀便、水样便最多,分别占病例总数的74.48%和21.07%;不同致病菌所引起的大便性状改变不同;副溶所致腹泻占80%以上;可疑饮食史主要是海水产品、肉及肉制品、淡水产品及果蔬类。结论腹泻病的临床症状、病原学及可疑饮食史对此病的诊治、预防有着非常重要的意义,要加强食源性疾病网和食品污染物监测网"两网"监测。OBJECTIVE To learn the epidemiological characteristics and its prevalent strains of diarrhea cases with pathogens from intestinal clinic,and to povide preventing bases for infectious diarrhea.METHODS We collected diarrhea cases with positive pathogens test,from the intestinal clinics in first class and second class hospitals,then investigated the clinical symptoms and food history,and analyzed the the pathogens testing results.RESULTS We collected 337 diarrea cases in this study,with average diarrea frequency as 5.87 times before treating;The patients had different extent stool changes,of which loose stools and watery stools covered most population,74.48% and 21.07% seperately.Different pathogens caused different stool changes.Vibrio parahaemolyticus occupied 80% of the positive pathogens tested.The suspicious food history mainly contained seafood,meat and meat products,freshwater products,fruits and cegetables.CONCLUSION Since the clinic symptoms,pathogen test and suspicious food history are very important for the diagnosis,treatment and prevention for diarrhea,so we should reinforce the survaillence of foodborne diseases and food pollutants.
