Abstract Fecal streptococci in marine water samples have been detected according to the Membrane Filtration (MF) technique on three agarized media (KF agar, M-Enterococcus agar, and Pfizer Selective Enterococcus agar), and according to the MPN methodology (Azide Dextrose broth followed by Ethyl Violet Azide Dextrose broth). Results show that these various media and techniques yield different figures. The lowest counts have been obtained with KF- agar and MPN technique. A high incubation temperature (44 °C) generally reduces the number of fecal streptococci recoveries with the only exception of KF agar. All the aforementioned systems used in this study to select fecal streptococci from sea water have shown a poor selectivity. However the highest recoveries of strictly named fecal streptococci have been found on KF agar. Two of the tested methods, MPN and MF on M-Enterococcus agar have been set by the European Economic Commission for detecting fecal streptococci in bathing waters. Results according to MPN are lower than those achieved on M-Enterococcus agar; however, they are well correlated with each other.
