【摘要】 目的了解上海市浦东新区某三级医院肠道门诊食源性腹泻病例的流行病学特征,为制定相应的防治对策提供科学依据。方法收集2013年8月—2014年8月浦东新区某大型三级综合性医院肠道门诊的腹泻病监测资料,进行流行病学分析,同时采集粪便/肛拭样本,进行病原学检测。结果 310例食源性腹泻病例中,主要可疑食物为肉类与肉制品115例(37.1%)、果蔬类86例(27.7%)、水产品68例(21.9%),86%的患者就餐地点为家里和餐饮店。采样182例,检出阳性菌株32例,其中致泻性大肠杆菌16例,阳性率为8.80%;沙门菌8例,阳性率为4.40%;副溶血性弧菌8例,阳性率为4.40%。结论患者中致泻性大肠杆菌、沙门菌和副溶血性弧菌的检出率较高,同时肉类和肉制品、果蔬类和水产品是可能的污染食品。更多还原

【Abstract】 Objective To discuss the microbiology and epidemiology in food-borne diarrhea cases in a 3-A hospital in Pudong New Area,so as to provide evidence for prevention measures. Methods The data on food-borne diarrhea cases was collected from August 14,2013 to August 13,2014 in a 3-A general hospital in Pudong New Area and its prevalent features were analyzed with descriptive epidemiologic methods. Stool samples were collected to detect pathogenic bacteria. Results Of the 310 food-borne diarrhea cases,the main suspected food categories were meat and its products( n = 115,37. 1%),vegetables and fruits( n = 86,27. 7%) and seafood( n = 68,21. 9%). In 182 stool samples collected,32 pathogenic strains were detected. The main bacteria was The diarrheagenic Escherichia coli( n = 16,8. 80%),Salmonella( n = 8,4. 40%),and Vibrio parahaemolyticus( n = 8,4. 40%). Conclusion Food-borne diarrhea cases found in this 3-A hospital were mainly caused by bacteria as the diarrheagenic Escherichia coli,Salmonellas and Vibrio parahaemolyticus. And meat and its products,vegetables and fruits were possible contaminated food.更多还原
