Thermo Scientific™ Azide Dextrose Broth (Dehydrated)

Description

Detect enterococci in water and sewage samples with this selective medium.

Detect enterococci in water and sewage samples with Thermo Scientific™ Oxoid™ Azide Dextrose Broth (Dehydrated). 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.

Azide Dextrose broth is recommended for the detection of enterococci in water and sewage⁴.

• Selective: sodium azinde in the medium acts as an inhibitor of Gram-negative organisms while providing optimum protection to enterococci.
• Recommended for the quantitative determination of enterococci in water, sewage, foods and other materials suspected of contamination with sewage¹.
