本研究的目的是开发和评估一种简单的膜过滤方法，用于浓缩和计数原水和成品饮用水中的F-特异性大肠杆菌噬菌体，以期将这些噬菌体用作病毒指示物。通过测定几种水源水中F-特异性大肠杆菌的浓度，并将其与粪便指示菌的浓度进行比较，对开发的方法进行了现场测试。结果表明，新的膜过滤法用于计数F-特异性大肠杆菌噬菌体，对于评估自然和处理过的水的粪便污染应该是有用的。还需要进一步的研究来确定这些大肠杆菌噬菌体是否是水中肠道病毒的可靠指标。 包括25个参考文献、表格和图表。

The purpose of this study was to develop and evaluate a simple membrane filter method for concentrating and enumerating F-specific coliphages in raw and finished drinking water with a view to using these phages as a viral indicatory. The method developed was fieldtested by determining the concentrations of F-specific coliphages in several source waters and comparing them with concentrations of fecal indicator bacteria. The results suggest that the new membrane filter method for enumerating F-specific coliphages should be useful for assessing fecal contamination of natural and treated waters. Additional studies are needed to determine whether these coliphages are reliable indicators of enteric viruses in water. Includes 25 references, tables, figures.
