Design and performance of a new medium for the quantitative recovery ofStaphylococcus aureusfrom recreational waters

摘要

Several reports have suggested that staphylococci, and especiallyStaphylococcus aureus, are useful indicators of pollution of recreational waters. The lack of a selective, accurate and reliable recovery system for the quantification ofStaph. aureusfrom water has been the principal obstacle to the evaluation of their use as indicators. In this study, several inhibitory substances and different nutrient sources have been evaluated for the formulation of a new selective medium. The medium designed, BFR‐0 agar, recovers more than 75 of staphylococci and allowsStaph. aureusto be identifie
