• A blend of peptone and glucose in the medium renders Azide Dextrose Broth highly nutritious, and sodium chloride maintains the osmotic equilibrium
• Sodium azide acts as an inhibitor of Gram-negative organisms 1,2,3 and the concentration of sodium azide used in the medium provides optimum protection for the enterococci while largely suppressing the Gram-negative flora
• The phosphate buffer system controls pH
• Enterococci are part of the normal intestinal flora of human and animals
• They have been long recognized as important human pathogens and are becoming increasingly so
• The presence of enterococci serves as an indicator of fecal contamination
• Enterococci are better indicators than Escherichia coli of sewage pollution in chlorinated waters because they have a greater resistance to chlorine
