Escherichia coli serotype O157H:7 and five other fecal and nonfecal coliforms were tested for minimum and maximum temperatures for growth in E. coli medium by using a temperature gradient incubator with a mean temperature increment of 1.67 degrees C (+/- 0.392). The temperature range for growth of E. coli O157:H7 is inconsistent with that of other fecal coliforms, suggesting that this pathogen is excluded with standard enumeration procedures used for foods and water.
利用平均温度增量为1.67摄氏度(±0.392)的温度梯度培养箱,对大肠杆菌O157:H7血清型以及其他五种粪便和非粪便大肠菌群在大肠杆菌培养基中的最低和最高生长温度进行了测试。大肠杆菌O157:H7的生长温度范围与其他粪便大肠菌群的不同,这表明在用于食品和水的标准计数程序中该病原体被排除在外。
