【摘要】：目的对参加国家食品安全风险监测的32个省级疾病预防控制中心,开展金黄色葡萄球菌定量、致泻性大肠埃希菌和未知肠道致病菌定性的质量控制考核,以评价其微生物检验技术能力。方法制备2种浓度的金黄色葡萄球菌样品。制备4种不同血清型的致泻性大肠埃希菌和未知肠道致病菌样品。金黄色葡萄球菌报告结果计算均值和标准差,利用Z比分做出满意与否评价。致泻性大肠埃希菌和未知肠道致病菌的结果评价为正确或者错误,没有报告结果的评价为缺失。结果金黄色葡萄球菌的满意率为82.81%;致泻性大肠埃希菌的正确率为45.16%;未知肠道致病菌考核中,沙门菌血清型的正确率为90.63%。3项考核均正确的率为28.13%。结论 32个省级疾病预防控制中心具备沙门菌鉴定和血清分型以及金黄色葡萄球菌定量检验能力,致泻性大肠埃希菌的血清分型能力有待加强。
[Abstract]:Objective to evaluate the quality control of Staphylococcus aureus quantitative, diarrhoeal Escherichia coli and unknown intestinal pathogenic bacteria in 32 provincial disease prevention and control centers participating in national food safety risk monitoring. To evaluate its microbiological testing technical ability. Methods two concentrations of Staphylococcus aureus samples were prepared. Four different serotypes of cathartic Escherichia coli and unknown intestinal pathogenic bacteria were prepared. Staphylococcus aureus reported results calculated mean and standard deviation, using Z score to evaluate satisfaction. The results of cathartic Escherichia coli and unknown intestinal pathogens were evaluated correctly or wrongly, and no reported results were evaluated as missing. Results the satisfactory rate of Staphylococcus aureus was 82.81 and the correct rate of diarrhea Escherichia coli was 45.16. In the examination of unknown intestinal pathogenic bacteria, the correct rate of Salmonella serotype was 90.63.3 and the correct rate was 28.13. Conclusion 32 provincial centers for disease prevention and control have the ability to identify Salmonella, serotyping and quantitative detection of Staphylococcus aureus, and the serotyping ability of diarrhea Escherichia coli needs to be strengthened.
