检测总大肠菌群和粪便大肠菌群的法国标准方法包括通过两个单独的膜对水进行膜过滤（MF），总大肠菌群和粪便大肠菌群分别在37℃和44℃下在TTC和特吉托乳糖琼脂上培养。虽然不需要色氨酸酶测试，但可以在粪便大肠菌群中鉴定大肠杆菌。对于地表水，基于44℃培养和选择β-葡萄糖醛酸酶阳性菌株的微孔板试验已在法国标准化，并正在国际水平上进行标准化。除了这些标准方法外，Colilert（R）field技术还可以用作存在/不存在测试，或者其结果可以通过多管最可能数（MPN）版本进行量化。 最近，Quanti托盘装置已被引入水中总大肠菌群和大肠杆菌的定量。本研究的目的是评估Colilert/QuantiTray法计数总大肠菌群和大肠杆菌的可靠性，并将所得结果与膜过滤法和微孔板法进行比较。

The French standard method for the detection of total and fecal coliforms involves membrane filtration (MF) of water through two separate membranes which are incubated on TTC and tergitol lactose agar at 37 degrees C for total coliforms and 44 degrees C for fecal coliforms. A test for tryptophanase, though not required, may be performed to identify E. coli among the fecal coliforms. For surface waters, a microplate test, based on incubation at 44 degrees C and selection of beta-glucuronidase positive strains has been standardized in France and is in the process of standardization at the international level. As well as these standard methods, the Colilert(R) field technique can be used as a presence/absence test, or its results can be quantified by a multiple tube most probable number (MPN) version. Recently, the Quanti-Tray device has been introduced to quantify total coliforms and E. coli in water samples. The objective of this study was to assess the reliability of the Colilert/QuantiTray method for the enumeration of total coliforms and E. coli and to compare the results obtained with those of the membrane filtration and microplate methods.
