GLUCOSE AZIDE BROTH

Fecal Streptococcus is a group of bacteria normally present in large numbers in the intestinal tract of warm-blooded animals other than human. The fecal Streptococcus group consists of a number of species of the genus Streptococcus such as Streptococcus faecalis, Streptococcus faecium, Streptococcus avium, Streptococcus bovis, Streptococcus equines and others. They have been used with fecal coliforms to differentiate fecal contamination from humans and from that of other warm- blooded animals. They tend to persist longer in the environment than faecal coliforms. Glucose Azide Broth is recommended by Hannay and Norton for enumeration of faecal streptococci by MPN technique from water, sewage, foods and other materials suspected to be contaminated with sewage.
