disk diffusion test

disk diffusion test
disk sensitivity test a type of antimicrobial susceptibility test in which agar plates are inoculated with a standardized suspension of a microorganism and then antibiotic-containing disks are applied to the agar surface. Following overnight incubation, the diameters of the zones of inhibition or clearing surrounding the disks are measured to calculate how susceptible or resistant the microorganism is.
