摘　　要：目的掌握达州市腹泻病例中的沙门菌感染率和菌型分布,提高腹泻病例和暴发疫情的实验室检测能力。方法从监测点腹泻病例粪便(或肛拭法)中分离沙门菌并进行生物学鉴定。结果 4年共监测腹泻1 291例,检出沙门菌52株8个血清型,总感染率为4.03%。临床就诊和暴发疫情腹泻病例沙门菌感染率分别为1.24%和23.60%。检出肠炎和鼠伤寒沙门菌各15株和10株,分别引起腹泻暴发疫情7宗和4宗,是我市流行的主要沙门菌血清型和腹泻暴发疫情的主要致病菌,凉拌菜和卤肉制品是腹泻暴发的高危食品。结论达州市流行的沙门菌血清型别众多,做好沙门菌监测对提高腹泻爆发疫情的应急反应具有十分重要的现实意义。严格生熟操作分开,防止烹调后食品的再次污染是减少食物中毒发生的重要措施之一。Objective To determine the infection rate, distribution of bacterium types associated with Salmo- nella among diarrhea cases in Dazhou City for the purpose of improving laboratory testing capability for diarrhea cases and outbreak. Methods The salmonella was isolated from diarrhea cases feces （or rectal swab） in surveillance sites and identified with biological approaches. Results 1 291 diarrhea cases were monitored in the past 4 years in total, among which 52 strains of Salmonella and 8 types of serotypes are detected. The overall infection rate was 4.03%. The infection rates of clinical cases and outbreak are respectively 1.24% and 23.60%. 15 strains of Salmonella enteri- tidis and 10 strains of Salmonella typhimurtum are detected, and respectively caused 7 and 4 diarrhea outbreak. They are the main serotypes and the main pathogenic bacteria of diarrhea outbreak. Salad and braised pork products are the high risk of diarrhea outbreak food. Gonclusion There are many serotypes in Dazhou, therefore, it is very important to monitor Salmonella and make preparation for the diarrhea outbreak. A most useful measure is to ensure dealing with the cooked and uncooked separately to prevent the repollution and to reduce poisoning.
