The inhibition zone
WebLarger zones of inhibition indicate that the pathogen of interest has a low resistance (high sensitivity) to the antibiotic of interest. In contrast, smaller zones of inhibition are indicative of high antibiotic resistance (low sensitivity). The results are used to determine the appropriate antibiotic or method of treatment of the infection. WebJul 31, 2024 · The zone of inhibition is a uniformly circular zone of no bacterial growth around the antibiotic disk. The larger this zone is, the more sensitive the bacteria is to that antibiotic. The smaller the zone is, the more resistant (and, thus, less sensitive) the … Most strains of E. coli are harmless, but some cause food poisoning in humans. …
