中文摘要:

      目的 通过参加中国食品药品检定研究院组织的副溶血性弧菌检验能力验证活动, 提高实验室检测副溶血性弧菌的准确率。方法 对能力验证标号为CODE1~CODE3的3组鱼蛋白粉样品, 使用恒温荧光核酸技术与国标GB 4789.7-2013食品安全国家标准 食品微生物学检验 副溶血性弧菌检验进行副溶血性弧菌的检测。结果 使用恒温荧光核酸检出CODE2为阳性结果, 与GB 4789.7-2013国家标准方法检出的阳性结果一致, 证明CODE2为副溶血性弧菌。结论 通过此次能力验证, 使得实验室副溶血性弧菌的检测能力得到了有效提高, 为快速检测副溶血性弧菌提供参考。

英文摘要:

      Objective To improve the accuracy of laboratory detection of Vibrio parahaemolyticus by participating in the proficiency testing organized by National Institutes for Food and Drug Control. Methods Vibrio parahaemolyticus was detected by thermostatic fluorescence nucleic acid technology and national standard GB 4789.7-2013 National food safety standard-Food microbiological analysis-Vibrio parahaemolyticus test in 3 groups of fish protein powder samples with CODE1-CODE3 for proficiency testing. Results CODE2 was detected as a positive result by thermostatic fluorescence nucleic acid, which was consistent with the positive result detected by GB 4789.7-2013 national standard method, proving that CODE2 was Vibrio parahaemolyticus. Conclusion Through this proficiency testing, the detection ability of Vibrio parahaemolyticus in the laboratory has been effectively improved, providing a reference for rapid detection of Vibrio parahaemolyticus.
