Tergitol-7 Agar was originally designed by Chapman and later on modified by incorporating 2,3,5-Triphenyl Tetrazolium Chloride (TTC) into the medium. This medium is selective and differential used for the detection and enumeration of coliform organisms. Pollard has reported the selective bactericidal property of sodium heptadecyl sulphate (Tergitol-7). Kulp et al corroborated the use of Tergitol-7 Agar with TTC in routine analysis of water and Mossel used this medium for the examination of food materials. Tergitol-7 Agar H, is a modification of Chapman formulation used for selective isolation and differentiation of enteric bacilli from urine samples. It contains sodium thiosulphate as an indicator of H2S production. H2S producing bacteria form black colonies or colonies with black centres.
