title: Quantitative determination of Escherichia coli from coliforms and faecal coliforms in sea water.
abstract: Escherichia coli concentration in sea water was determined by the MUG test after primary growth on membrane filters used to determine total coliforms or faecal coliforms. A good correlation (r = 0.86) was found between E. coli obtained from coliforms versus those from faecal coliforms. Verification procedures showed that all the MUG-positive colonies obtained on both media were E. coli. Evaluation of this data and the literature indicated that this technique for estimation of E. coli in sea water is a useful addition to laboratory procedures without generally increasing the time and the expense of the analysis of recreational water.
