1 R = resistant, 2 S = sensitive, 3 one isolate was sensitive in the disk diffusion assay (diameter = 25 mm), but resistant in the MIC (Minimal Inhibitory Concentration) test strip (MIC = 6 μg/mL) and the second isolate was resistant in the disk diffusion assay (diameter = 18 mm), but sensitive in the MIC test (MIC = 4 μg/mL), 4 this isolate was resistant in the disk diffusion assay (diameter = 9 mm), but sensitive in the MIC test (MIC = 4 μg/mL).
