Description

Application

Salmonella ChromoSelect Agar is a selective medium used for simultaneous detection of Escherichia coli and Salmonella from food and water. Escherichia coli and Salmonella are easily distinguishable due to the colony characteristics. Salmonella give light purple colonies a halo. Escherichia coli has a characteristic blue color, other organisms give colorless colonies. The characteristic light purple and blue color is due to the chromogenic mixture.

Preparation Note

Suspend 27.9 g in 1 litre distilled water. Boil gently to dissolve the medium completely. DO NOT AUTOCLAVE. Cool to 50°C. Mix well and pour into sterile petri plates.
