Determination of inhibition zone diameter in the antibiotic disc diffusion tests. Interpretation is based on the EUCAST breakpoints; isolates categorized as susceptible to norfloxacin (S ≥ 17 mm) can be reported as “susceptible increased exposure” to ciprofloxacin (R ˂ 21 mm, S ≥ 50 mm) (see Table 2), vancomycin (R ˂ 10 mm, S ≥ 10 mm), netilmicin (R ˂ 18 mm, S ≥ 18 mm), nitrofurantoin (R ˂ 13 mm, S ≥ 13 mm), gentamicin (R ˂ 18 mm, S ≥ 18 mm), chloramphenicol (R ˂ 18 mm, S ≥ 18 mm), clindamycin (R ˂ 19 mm, S ≥ 22 mm), erythromycin (R ˂ 18 mm, S ≥ 21 mm), and tetracycline (R ˂ 19 mm, S ≥ 22 mm).
