Abstract
This study shows that colony diameter exceeding 0.5 mm and presence of a surrounding precipitation zone are not unconditional criteria for 44 degrees C coliforms (Escherichia coli and Klebsiella species) grown on violet red bile agar. Confirmatory studies in brilliant green lactose bile broth will add to the numbers of coliforms which are missed if these criteria are adhered to.
摘要
本研究表明，对于在紫红胆盐琼脂上生长的44℃大肠菌群（大肠杆菌和克雷伯菌属），菌落直径超过0.5毫米以及存在周围沉淀带并非无条件适用的标准。如果坚持这些标准，在煌绿乳糖胆盐肉汤中进行的验证性研究将会增加漏检的大肠菌群数量。
