目的通过参加微生物质控考核,了解实验室细菌鉴定能力。方法按照《食品安全国家标准食品微生物学检验》对2支食源性致病菌的混合盲样菌株进行分离培养鉴定。结果根据细菌的生长特点、形态学观察和生物学特征来判断,001号检出出血性大肠埃希菌和乙型副伤寒沙门菌,100号检出蜡样芽胞杆菌。结论两支混合盲样菌株鉴定正确,通过盲样菌株的鉴定再次提高了检测人员的检测水平。 Objective To understand the laboratory bacteria identification ability by participating in the microbiology control test. Methods According to the National Food Safety Standard Microbiological Examination, the mixed blind-like strains of 2 food-borne pathogens were isolated and identified. Results According to the growth characteristics, morphological observation and biological characteristics of bacteria, hemorrhagic Escherichia coli and paratyphi B were detected in 001 and Bacillus cereus were detected in 100. Conclusion The two mixed blind-like strains were identified correctly. The identification of blind-like strains raised the detection level again.
