During the discussion of a paper presented by the author to the Society for Water Treatment and Examination at Sheffield in 1952, it was noted that several water bacteriologists were confirming, with a high degree of success, presumptive positive tubes in the coliform test as Bacterium coli type I after incubation for 6 hr. only in MacConkey broth at 44° C. (Taylor, 1952).
