Antimicrobial susceptibilities to the various antibiotics of 251 gram-negative bacteria isolated from hospital infections were detected by agar dilution and E-test methods. Escherichia coli was the most common isolate among the gram-negative bacteria (31.8%). The others, isolated were respectively as Pseudomonas aeruginosa (29.5%), Acinetobacter baumannii (18.3%) ve Klebsiella spp. (13.2%). Meropenem, ciprofloxacin and cefoperazone-sulbactam were detected the most efficient three antibiotics against enteric gram-negative bacteria. In the nonfermentative group, the most efficient antibiotics were ciprofloxacin, cefoperazone-sulbactam and piperacillin-tazobactam for P. aeruginosa; and meropenem, cefoperazonesulbactam and ciprofloxacin for A. baumannii.
