In this prospective study, we found that 21.80% (29/133) of nosocomial urinary tract infections (NUTis) were caused by Escherichia coli, 12.78% (17/133) by Pseudomonas aeruginosa and 10.53% (14/133) by Klebsiella pneumoniae whereas 16.54% (22/133) were caused by coagulase negative staphylococci. The highest susceptibility rate was determined with imipenem among gram negatives (21/28 for non-fermentatives and 65/66 for others); and with vancomycin (30/30) and pristinamycin (29/30) among gram positives. On the other hand, the lowest susceptibilities were to amoxicilin (7/66), amoxicilin clavulonat (18/66) and cotrimoxazole (27/66) among gram negatives other than non-fermentatives. All of the non-fermentative gram negative isolates were resistant to gentamicin (30/30). Most of the P. aeruginosa strains (15/17) were isolated from samples of catheterized patients. Because of their poor susceptibility rates, cotrimoxazole, penicilins and gentamicin shouldn't be administered empirically, especially to catheterized patients with NUTIs
