"Samples of drinking water from five different distribution line sources in Lima, Peru, were tested for total coliforms, fecal coliforms and coliphage populations. The P/A and H2S paper strip methods were equally or more sensitive for the presence of indicator bacteria than the TC/FC MEN test. In 20% of the samples, the only indicator organisms present were coliphage. The incidence of coliphage in these potable water supplies reflects the probability of human pathogenic virus presence"--Abstract.
