  • a micro-organism is defined as resistant (R) by a level of antimicrobial exposure associated with a high likelihood of therapeutic failure.

Clinical breakpointsf1 are presented as:

  • S: MIC ≤ x mg/L; disk diffusion zone diameter ≥ σ mm

  • I: MIC > x, ≤ y mg/L; disk diffusion zone diameter ≥ ρ mm, < σ mm

  • R: MIC > y mg/L; disk diffusion zone diameter < ρ mm
