目的掌握广西贵港市从业人员沙门菌携带状况,为制订本市肠道传染病防治规划提供依据。方法对2006～2008年在本中心进行健康体检人员的肛拭标本,按照GB/T4789-2003标准检测沙门菌,针对带菌者的流行病学特点进行分析。结果检测标本37597份,检出沙门菌阳性标本83份,检出率为0.22%;各年检出率分别为0.16%、0.35%、0.15%;36个月中有25个月检出沙门菌,占69.44%;每年2、3季度带菌率最高;带菌率随年龄增长升高;男女带菌率差别有统计学意义,χ2=7.38,P<0.005;3年检出的服务点有71个,其中仅有1人带菌的服务点有62个,占87.32%。结论贵港市从业人员沙门菌携带者的流行病学特点,在时间、年龄、性别、服务点的分布上都非常分散、隐蔽,并能正常工作,当食品、饮用水受其粪便污染时,可发生群体性食物中毒;提示沙门菌监测工作是一项极为严峻、艰巨而又十分重要的工作。
Objective To understand the carrying status of Salmonella among practitioners in Guigang, Guangxi and provide evidence for the prevention and control of intestinal infectious diseases in this city. Methods The samples of anal swabs from 2006 to 2008 in our health examination center were tested according to the standard of GB / T4789-2003, and the epidemiological characteristics of carriers were analyzed. Results A total of 37597 samples were detected, of which 83 were positive for Salmonella, the detection rate was 0.22%. The detection rates were 0.16%, 0.35% and 0.15% in each year respectively. Salmonella was detected in 25 of 36 months , Accounting for 69.44%; the second and third quarters of each year the highest rate of carrier bacteria; carrier rate increased with age; male and female carrier rates were significantly different, χ2 = 7.38, P <0 005; Among them, there are 62 service points carrying only one person, accounting for 87.32%. Conclusion The epidemiological characteristics of the carriers of Salmonella in Guigang City are very scattered, hidden and can work normally in time, age, sex and distribution of service points. When food and drinking water are polluted by their excrement, The occurrence of mass food poisoning; prompt Salmonella monitoring is a very serious, arduous and very important work.
