奶粉中病原菌质控考核结果分析
目的 对质控考核样品进行检测, 分离鉴定肠杆菌科志贺氏菌属A群痢疾志贺氏菌和金黄色葡萄球菌, 并分析其中特别的生物学现象。方法 按照《食品安全国家标准 食品微生物学检验 (GB 4789.5-2012)》对考核检样进行检测。结果 分离出宋内志贺氏菌而未分离出金黄色葡萄球菌, 并在检验过程中观察到特别的生物学现象。结论 志贺氏菌在志贺氏菌属显色培养基上并非显示一样颜色, 有白色菌落周围培养基显示紫红色,也有黄色菌落周围培养基显示黄色。
Objective To separate Shigella dysenteriae and Staphylococcus aureus from quality-control samples, and analyze their biological phenomenon.
