Principle and Interpretation The Mueller Hinton formulation was originally developed for the cultivation of pathogenic Neisseria species (1). Other media were subsequently developed that replaced the use of Mueller Hinton Agar for the cultivation of pathogenic Neisseria species, but it became widely used in the determination of sulfonamide resistance of gonococci and other organisms. Mueller Hinton Agar is now used as a test medium for antimicrobial susceptibility testing (2). Acicase provide nitrogenous compounds, carbon, sulphur and other essential nutrients. These ingredients are selected for low thymine and thymidine content as determined by MIC values for Enterococcus faecalis with sulfamethoxazole trimethoprim (SXT). Chromogenic mixture incorporated helps in colour differentiation. One of the chromogenic substrate is cleaved by b-glucosidase possessed by Enterococci resulting in formation of blue colonies. E.c...
