For antimicrobial susceptibility testing of bacterial cultures by disk diffusion method of Bauer-Kirby.
Disc diffusion test is a qualitative test method. This method is based on the principle that antibiotic-impregnated disk, placed on agar previously inoculated with the test bacterium, picks up moisture 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 purpose of the Antimicrobial susceptibility testing (AST) by Kirby-Bauer disk diffusion susceptibility test is to determine the sensitivity or resistance of pathogenic microbes to various antimicrobial compounds.
