• non-fermenting gram-negative bacilli
• pseudomonas aeruginosa
• antimicrobials.

introduction: the non-fermenting gram-negative bacilli (nfgnb) have been widely associated with nosocomial infections. not only are these microorganisms highly prevalent but they are also highly resistant to nfgnb. objective: to assess the prevalence and resistance profile of non-fermenting gram-negative bacilli. methods: 14.971 patient reports from a private hospital in porto alegre, rio grande do sul, from may/2006 to march/2008 were analyzed. results and conclusion: three hundred twenty-six samples of non-fermenting gram-negative bacilli were isolated. the most prevalent species were pseudomonas aeruginosa (65.03%), acinetobacter baumannii (16.56%), and stenotrophomonas maltophilia (9.5%). other species showed rates lower than 5%. the microorganisms were isolated from several infectious sites and the biological materials that showed higher positivity were the following: tracheal aspirate (38.34%), spittle (18.71%) and urine (15.95%). bacterial resistance was higher with tetracyclines (89.57%) and sulfamethoxazole/trimethoprim (79.75%). the most active antimicrobials were polymyxin b and piperacillin/tazobactam with 100% and 75.2% sensibility, respectively.
