Glucose Azide Broth

Glucose Azide Broth is used for the enumeration of faecal Streptococci by MPN technique from water, sewage,foods and other materials suspected to be contaminated with sewage. Fecal Streptococcus is a group of bacteria normally present in large numbers in the intestinal tract of warm-blooded animals other than human. They have been used with fecal coliforms to differentiate fecal contamination from humans and from that of other warmblooded animals. They tend to persist longer in the environment than faecal coliforms.
