Keywords: Urine culture, antimicrobial susceptibility

The aim of this study was to evaluate the microorganisms isolated from urine samples and their antimicrobial susceptibilities which were sent to Central Microbiology Laboratory of Akdeniz University Hospital between January 2003 and December2003. Among 37767 cultured urine samples, 3171 (8.4%) were positive. Within 3171 positive cultures, 2692 (84.9%) were Gram negative and 479 (15.1%) were Gram positive. While the most frequent Gram negative bacteria isolated from urine samples were Escherichia coli (45.2%), Klebsiella sp. (17.6%) and Pseudomonas sp. (8.5%), Gram positives were Enterococcus sp. (10.9%), Staphylococcus aureus (1.8%), Streptococcus agalactiae (1.6%) respectively. For E. coli and Klebsiella sp. the most effective antimicrobial agents were carbapenems and amikacin; for Pseudomonas sp. the most effective antimicrobials were piperacillin-tazobactam and meropenem. It was found that glycopeptides and nitrofurantoine were the most effective antibiotics for enterococci. The identification of the microorganisms and the nature of their antimicrobial susceptibilities is thought to be important for the medical centers to determine their own antimicrobial usage policies.
