BROMO CRESOL PURPLE AZIDE BROTH

Description

Enterococci are widely distributed and occur in different habitats. The Enterococci portion of the faecal Streptococcus group is a valuable bacterial indicator for determining the extent of faecal contamination of recreational surface waters. Studies indicate that swimming associated gastroenteritis is related directly to the quality of bathing water and that enterococci are the most efficient bacterial indicators of water quality. Bromo Cresol Purple Azide Broth formulated as per Hajna & Perry is used for the confirmation of the presence of faecal streptococci in water and wastewater. This medium is used for testing water samples, after preliminary testing of water samples in Azide Dextrose broth. Bromo Cresol Purple Azide Broth is recommended by APHA for enumerating faecal streptococci by the MPN technique.
