Abstract

The capability of coliphages as indicators of faecal pollution was tested, on the basis of their survival and infectivity in two natural aquatic environments (marine and river). The results obtained indicate that coliphages show a similar inactivation rate to Salmonella in all types of water studied. On the other hand, the phage productive infection of Escherichia coli cells in water and environmental conditions depends on the physiological characteristics of the host bacteria, which generally cannot grow optimally in these conditions. In conclusion, the coliphages may be considered good indicators of faecal pollution in natural waters.

      Some of these may occur in pristine waters, so exceptionally somatic coliphages may also multiply in these environments. In addition, they have been reported to replicate in E. coli under environmental conditions (Vaughn and Metcalf, 1975; Seeley and Primrose, 1980; Borrego et al., 1990). Therefore, one of the potential drawbacks of somatic coliphages has been their potential replication outside the gut.
