目的对桂林市2004～2006年细菌性食物中毒病原菌的分布特征与规律进行分类统计分析,为建立食物中毒病原菌的主动监测提供科学依据。方法对30起引起细菌性食物中毒病原菌检测数据进行统计分析,按照国家卫生标准方法进行病原菌检验。结果30起细菌性食物中毒事件检测各类样品562份,检出病原菌126株,总检出率为22.4%。其中致泻大肠埃希氏菌检出率为8.2%,蜡样芽孢杆菌为5.5%,变形杆菌为4.1%,金黄色葡萄球菌为3.6%,副溶血弧菌为1.1%。各类样品中以病人呕吐物和肛拭检出率最高,分别为55.6%和51.4%;其次是剩余食品,检出率为45.5%。8～10月为高峰。结论2004～2006年桂林市细菌性食物中毒病原菌以致泻性大肠埃希氏菌(主要是EPEC)为主,其次为蜡样芽孢杆菌和变形杆菌.
Objective To classify and analyze the distribution characteristics and laws of pathogenic bacteria of bacterial food poisoning in Guilin from 2004 to 2006, and to provide a scientific basis for establishing the active monitoring of pathogenic bacteria of food poisoning. Methods The data of 30 pathogenic bacteria causing bacterial food poisoning were statistically analyzed and the pathogen was tested according to the national standard of health. Results A total of 562 samples of various types of bacterial food poisoning were detected. 126 pathogens were detected with a total detection rate of 22.4%. The detection rate of diarrhea Escherichia coli was 8.2%, Bacillus cereus 5.5%, Proteus 4.1%, Staphylococcus aureus 3.6%, Vibrio parahaemolyticus 1.1%. The highest detection rates of vomitus and anal swab in all kinds of samples were 55.6% and 51.4% respectively, followed by the remaining food with a detection rate of 45.5%. 8 to October for the peak. Conclusion The pathogens of bacterial food poisoning in Guilin from 2004 to 2006 were mainly diarrheogenic Escherichia coli (mainly EPEC), followed by Bacillus cereus and Proteus.
