Why MHA is used for antibiotic susceptibility testing?

Why MHA is used for antibiotic susceptibility testing

Answer: It is a non-selective, non-differential medium. This means that almost all organisms plated on here will grow. It contains starch. Starch is known to absorb toxins released from bacteria so that they cannot interfere with the antibiotics. It also mediates the rate of diffusion of the antibiotics through the agar. It is a loose agar. This allows for better …

Introduction of Mueller Hinton Agar (MHA) Mueller and Hinton developed Mueller Hinton Agar (MHA) in 1941 for the isolation of pathogenic Neisseria species. Mueller Hinton agar is a microbiological growth medium that is commonly used for antibiotic susceptibility testing using  Kirby-Bauer disc diffusion method. MHA is recommended for the diffusion of antimicrobial agents impregnated on paper disc through an agar gel as described in CLSI Approved Standard. Zone diameters established for …
