Description
For the past fifty years, MacConkey Broth has been the standard medium for the primary isolation of coliform bacteria, and has been recommended for this purpose by the Public Health Laboratory Service Water Committee7 and the World Health Organization1. The Oxoid product conforms to their specification for water testing and also to the formulation specified by the Dept. of Health2 for milk grading.
The advantages of MacConkey Broth in the presumptive coliform test are the low proportion of false positive reactions (PHLS Water Subcommittee3) and the fact that most strains of Escherichia coli produce a positive reaction within 24 hours4. Disadvantages, due to variability of the peptone and bile salts contained in the original medium, have been overcome by large scale production, pooling of batches and careful quality control - including titrimetric standardisation of the bile salts by a method described by Burman5.
The neutral red is pre-tested for the absence of toxic substances before inclusion in the Oxoid medium. Childs & Allen6 have shown that some samples of neutral red were inhibitory. For those who prefer, this medium is also available with bromocresol purple as the indicator - for details of this alternative medium and the presumptive coliform test see MacConkey Broth Purple (CM0505).
