- Somatic coliphages have been proposed as indicators of water quality. But several factors have been considered a drawback for their use as indicators. We evaluated the contribution of temperate phages to the numbers of somatic coliphages detected in water by ISO (International Standards Organization) standardised methods. Prophage induction from naturally occurring bacteria was assayed with mitomycin C, ciprofloxacin and UV irradiation. Results indicate that the presence of prophages will not influence the determinations of somatic coliphages in water.
