MUG-lauryl sulfate bouillon--an optimal medium for the detection of total coliforms and fecal coliform bacteria in relation to hygienic evaluation of bathing waters according to the European Community Guideline 76/160 EWG

In the monitoring of bathing waters according to the EC-guideline, total coliform and faecal coliform bacteria were obtained from 97 samples of river waters by the comparison of two fluorogenic assays using MUG-Lauryl Sulfate Broth and MUG-BRILA Broth with an usual method with MacConkey Broth, Tryptophane Broth and BRILA Broth. MUG-BRILA Broth had the lowest average counts and proved to be not an appropriate medium. Compared with the usual method, however, MUG-Lauryl Sulfate Broth yielded similar high counts, reduced the investigation period from four to two days and diminished the expenditure of work by one third. In addition, the indole test for the confirmation of presumptive faecal coliforms might be abolished. Therefore, the examination with MUG-Lauryl Sulfate Broth can be recommended.
