TRYPTONE BILE AGAR

Tryptone Bile Agar was formulated by Anderson and Baird-Parker. The International Commission on the Microbiological Specifications for Foods (CMSF) compared the Most Probable Number (MPN) and the Anderson-Baird-Parker Direct Plating Method (DPM) and observed that DPM was superior to MPN for enumeration of Escherichia coli from raw meats. Superiority of DPM method was noticed by the organization on the basis of less variability, better recovery from frozen samples, greater rapidity and the smaller quantity of medium required.
