MIC values that indicate non-susceptibility to the antibiotic are shaded grey.
The %S is the number of susceptible isolates as a percentage of all isolates tested for each antibiotic.
MIC, minimum inhibitory concentration; CRO, ceftriaxone; FEP, cefepime; TIM, ticarcillin-clavulanic acid; PIP, piperacillin; MEM, meropenem; LVX, levofloxacin; TET, tetracycline; TGC, tigecycline; MIN, minocycline; nd, antibiotics not tested.
*Non-susceptibility inferred by the VITEK 2® AES system.
