Antimicrobials and break points* | Susceptible | Intermediate | Resistant |
---|---|---|---|
*In some instances (e.g. gentamicin) there is a range of MICs between the break points counting as intermediate; in others (e.g. ceftazidime) no intermediate range is recognised by BSAC.11 | |||

Tobramycin (⩽1; ⩾8) | 230 (55.1) | 145(34.6) | 42 (10.1) |
Ceftazidime (⩽8; ⩾16) | 252 (60.4) | – | 165 (39.6) |
Ciprofloxacin (⩽1; ⩾8) | 182 (43.6) | 111 (26.6) | 124 (29.7) |
