Antimicrobial Test (Inhibition Zone/Disc)

Antimicrobial test (Inhibition zone/disk) method is based on the principle that antibiotic-impregnated disk, placed on agar previously inoculated with the test bacterium, and the antibiotic diffuses radially outward through the agar medium producing an antibiotic concentration gradient. A clear zone or ring is formed around an antibiotic disk after incubation if the agent inhibits bacterial growth.
The disk diffusion method is performed using Mueller-Hinton Agar (MHA), the best medium for routine susceptibility tests. It has good reproducibility, low sulfonamide, trimethoprim, and tetracycline inhibitors, and gives satisfactory growth of most bacterial pathogens.
