a BAL, bronchoalveolar lavage; ETT, endotracheal tube. b For the calculation of resistance score, any resistant call was given a score of 1, while intermediate resistance was given a score of 0.5. c CTX, cefotaxime; TIC, ticarcillin; TIM, ticarcillin/clavulanate; PIP, piperacillin; TZP, piperacillin/tazobactam; CAZ, ceftazidime; FEP, cefepime; ATM, aztreonam; IPM, imipenem; MEM, meropenem; AMK, amikacin; GEN, gentamicin; TOB, tobramycin; CIP, ciprofloxacin; SXT, sulfamethoxazole/trimethoprim. Antibiotics to which the tested isolates showed intermediate resistance are in bold format.
