into the agar in a gradient, the antibiotic concentration will decrease as the distance from the disk increases. Antibiotic susceptibility is determined by measuring the diameter of the zones of bacterial inhibition around the antibiotic disks and comparing the diameter with disk diffusion interpretive criteria (Schwalbe, et al., 2007). See ...
