作者对苏联国定标准(ΓOCT)2874～73《饮水》中所推荐的检验方法作了评价。根据莫斯科许多防疫站的检验结果,作者发现往往水中大肠杆菌完全阴性,但按氧化酶(+)杆菌计算的大肠杆菌指数则超出卫生要求。根据生物化学研究,氧化酶(+)杆菌在37℃下能发酵葡萄糖,但不能分解乳糖使之产酸产气。它们在远藤培养基上呈现淡红色、白色及白-橙红色菌落,不发酵乳糖,少数则呈现红色菌落,
The authors evaluated the test methods recommended in the 2873-73 “Drinking Water” of the Soviet Union’s National Standard (ΓOCT). According to the results of many epidemic prevention stations in Moscow, the authors found that Escherichia coli in water was often completely negative, but the E. coli index calculated by oxidase (+) exceeded health requirements. According to biochemical studies, oxidase (+) bacteria ferment glucose at 37 ° C, but can not break down lactose to produce acid gas. They appear in Endo medium pink, white and white - orange-red colonies, not fermented lactose, a few are showing red colonies,
