Abstract
A selective membrane filtration medium is described for use in the rapid assessment of water quality in tropical countries where the incidence of faecal coliforms other than E. coli presents problems in the interpretation of results. The medium gives comparable results to MPN values obtained in the multiple tube dilution test using modified Gray's glutamate medium, and to membrane filtration counts obtained using M-FC broth and membrane-enriched Teepol broth, whilst differentiation of E. coli is enhanced.
摘要
本文描述了一种选择性膜过滤介质，用于热带国家水质的快速评估，在这些国家，除大肠杆菌外的粪大肠菌群的存在给结果解读带来了问题。该介质所得结果与使用改良格雷谷氨酸培养基的多管稀释试验中获得的MPN值相当，也与使用M-FC肉汤和膜富集的替波尔肉汤获得的膜过滤计数结果相当，同时增强了对大肠杆菌的鉴别能力。
