Both the PABA and thymine/thymidine content in Mueller Hinton Agar are reduced to a minimum, thus markedly reducing the inactivation of sulfonamides and trimethoprim when the media is used for testing the susceptibility of bacterial isolates to these antibiotics. Zone of inhibition is observed around the antibiotics. The standardized disc diffusion procedure is based on the ability of an antimicrobial agent impregnated on a paper disc to diffuse through agar gel. The addition of starch to Mueller Hinton Agar ensures that toxic factors found during growth will be absorbed, and its presence is often essential to establish growth from very small inocula. In vitro susceptibility does not necessarily imply in vivo effectiveness. J. Clin. Introduction of Mueller Hinton Agar (MHA).

Conforms to EUCAST, CLSI and DIN. 7. Pathol. It has become the standard medium for the Bauer Kirby method and its performance is specified by the NCCLS. The inoculation procedure is the same as for Mueller Hinton Agar except that Mueller Hinton Broth is recommended for the suspension (see "Method F" in "Inoculation Procedures for Media QC"). The addition of starch to Mueller Hinton Agar ensures that toxic factors found during growth will be absorbed, and its presence is often essential to establish growth from very small inocula. Cool to room temperature. (6) It was found that Mueller Hinton Agar was useful in identifying sulfonimide-resistant and responsive strains of gonococci. The impregnated disk is placed on an agar surface, resulting in diffusion of the antimicrobial into the surrounding medium. Effectiveness of the antimicrobial can be shown by measuring the zone of inhibition for a pure culture of an organism. This method was standardized for facultative organisms or rapid growing aerobes. away from direct light. Effect of storage of Mueller Hinton Agar plates on zone sizes for antimicrobial testing.
