|---|---|---|---|
| EUCASTa | CLSIb | BSACa | |
| Imipenem, meropenem | 2/8 | 4/16 | 2/8 |
| Ciprofloxacin | 1/1 | 1/4 | 1/1 |
| Levofloxacin | 1/2 | 2/8 | |
| Amikacin | 8/16 | 16/64 | |
| Gentamicin, tobramycin | 4/4 | 4/16 | 4/4 |
| Netilmicin | 4/4 | 8/32 | |
| Ampicillin-sulbactam | 8/32 | ||
| Piperacillin-tazobactam | 16/128 | 16/16 | |
| Ticarcillin-clavulanate | 16/128 | ||
| Ceftazidime, cefepime | 8/32 | ||
| Ceftriaxone, cefotaxime | 8/64 | ||
| Polymyxin B, colistin | 2/4 | ||
| Trimethoprim-sulfamethoxazole | 2/4 | ||
| Doxycycline, minocycline, tetracycline | 4/16 | ||
| Tigecycline | 1/2 | ||
a
For EUCAST and BSAC breakpoints, susceptibility is defined by a MIC equal to or lower than the first number and resistance is defined by a MIC greater than the second number.
b
For CLSI breakpoints, susceptibility is defined by a MIC equal to or lower than the first number and resistance is defined by a MIC equal to or greater than the second number.
