摘　　要：目的了解济宁市食源性腹泻病病原学分布特征及流行趋势,为预防和控制食源性腹泻病提供科学依据。方法对济宁市2014-2019年食源性疾病哨点医院上报采集的1646例病例腹泻标本进行诺如病毒、沙门菌、志贺菌、副溶血弧菌和致泻性大肠埃希菌检测分析。结果食源性腹泻病病原体检出率为30.87%(508/1646),其中诺如病毒检出率为16.89%(278/1646),分型以诺如Ⅱ型为主;细菌感染检出率为16.34%(269/1646),以致泻性大肠埃希菌为主,分型以肠出血性大肠埃希菌(EHEC)为主。不同年度(χ^(2)=111.67,P<0.01),不同季节(χ^(2)=31.20,P<0.01)病原体检出率差异有统计学意义;高危职业主要集中在托幼儿童和农民;可疑暴露食品居前三位的为混合食品(14.03%)、水果及其制品(13.06%)和粮食类及其制品(11.24%);进食场所以家庭为主。结论济宁市食源性腹泻病病原体主要为诺如病毒和致泻性大肠埃希菌,高危职业人群为托幼儿童和农民,可疑暴露食品为混合食品,水果、粮食及其制品。建议加强对食源性疾病病原的监测,不断完善监测体系,制定相应的防控措施,减少疾病的发生。Objective To understand the pathogen surveillance and epidemic characteristics of food-borne diarrhoeal disease in Jining,and to provide scientific basis for the prevention and control of food-borne diarrhoeal disease.Methods To detect and analyze of 1646cases collected for the norovirus,salmonella,Shigella,vibrio Parahemolyticus and diarrheagenic Escherichia coli(DEC)from food-borne sentinel hospitals in Jining City during 2014-2019.Results The positive detection rate of food-borne diarrhoeal diseases was 30.87%(508/1646),Among these,the positive rate of virus infection was 16.89%(269/1646),and the main viral pathogen was GⅡ;the positive rate of bacterial infection was 16.34%(269/1646),and the main bacterial pathogen was enterohem-orrhagic escherichia col(EHEC).The detection rates of pathogens in different years(χ^(2)=111.67,P<0.01)and seasons(χ^(2)=31.20,P<0.01)were statistically significant.Child care children and farmers were the main occupation;the top three of suspected exposure foods were grain products(14.03%),fruits and fruit products fruits(13.06%),and mixed foods(11.24%).Suspicious eating place were families.Conclusion The pathogens of food-borne diarrhea in Jining city were mainly norovirus and DEC.The high-risk occupational groups were child care children and farmers.The suspicious foods were mixed food and fruit,grain and its products.It is suggested to strengthen the monitoring of food-borne diseases pathogens,constantly improve the monitoring system,formulate corresponding prevention and control measures to reduce the occurrence of diseases.
