Agar disc diffusion assay
WebGradient diffusion testing. Gradient diffusion testing is used when it is important to know the precise MIC for a given pathogen-antibiotic combination. Usually, commercial MIC gradient test strips are used. These have a high concentration of antimicrobial at one end of the strip, and the concentration gradually decreases along the length of ... The disk diffusion test (also known as the agar diffusion test, Kirby–Bauer test, disc-diffusion antibiotic susceptibility test, disc-diffusion antibiotic sensitivity test and KB test) is a culture-based microbiology assay used in diagnostic and drug discovery laboratories.
