Water quality. Detection and enumeration of bacteriophages - Enumeration of bacteriophages infecting <i>Bacteriodes fragilis</i>1 Scope This part of ISO 10705 specifies a method for the detection and enumeration of bacteriophages infecting Bacteroides fragilis by incubating the sample with an appropriate host strain. The method is applicable to all kinds of water, sediments and sludge extracts, where necessary after dilution.
