[Indicatory role of coliphages in relation to contamination of drinking water by enteroviruses].

It has been found out that a coli-phage is a more reliable indirect indicator of viral pollution of drinking water that the existing indirect bacterial indicators. Coli-phages concentration in drinking water on the level of single PFU/1 is evidence of disturbances in the barrier function of water-treatment facilities with respect to viral microflora and of the possible epidemic danger of water with respect to viral infection. The absence of coli-phages in I 1 of water sample should be considered the standard level of coli-phages of drinking water.
