Mueller Hinton Fastidious Agar (Horse blood 5% + 20 mg/L β-NAD) is recommended by EUCAST for antimicrobial susceptibility testing of Streptococcus spp (including S. pneumoniae), Haemophilus spp and several other fastidious organisms. Both the para-aminobenzoic acid (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 antimicrobics. Fast-dissolving powders come premixed for quick preparation using neutral liquids. Mueller Hinton Agar is now used as a test medium for antimicrobial susceptibility testing (9). Starch is added to absorb any toxic metabolites produced. Where studies on antibiotic susceptibilities are being undertaken both in broth and agar, it will be found to be of particular value to have media of identical nutrient formulation. What is Mueller Hinton Agar (MHA) ? It is specified in FDA Bacteriological Analytical Manual for food testing, and procedures commonly performed on aerobic and facultative anaerobic bacteria. Cool to room temperature. The use of a suitable medium for testing the susceptibility of microorganisms to sulfonamides and trimethoprim is essential. A precise clear zone will help to determine if the bacteria is resistant or sensitive to the antibiotics used. This allows for better diffusion of the antibiotics than most other plates. Medium Mueller Hinton Agar (MHA) mengandung sulfoamida, trimethoprim, dan inhibitor tetrasiklin yang rendah sehingga mendukung pertumbuhan bakteri non-fastidious yang bersifat patogen.
