WebHopefully your control disc, containing only water, should show no zone of inhibition. Depending on the antimicrobial agent that you have used, you would expect different levels of growth inhibition. Going back to the example of penicillin, we would expect a much larger inhibition on the growth of S. aureus than on E. coli , as S. aureus is gram-positive and E. … WebZone diameters of antimicrobial agents according to CLSI guidelines 2011 Zone diameters are in mm Antimicrobial agent Disc content When testing Susceptible Intermediately susceptible Resistant Acinetobacter spp ≥17 15-16 ≤14 Enterobacteriaceae ≥17 15-16 ≤14 Pseudomonas aeruginosa ≥17 15-16 ≤14 Amikacin 30 µg WebAntibacterial activity is observed as a clear circular zone of inhibition around the drug-impregnated disk, similar to the disk-diffusion assay depicted in Figure 13.31.
