ABSTRACT

The aim of this study was to obtain data on susceptibility patterns of Escherichia coli strains responsible for community acquired urinary tract infections in a private hospital in Istanbul, Turkey.

Between the dates of 1 January 2008 and 31 December 2008 patients admitted to the urology outpatient department with suspected urinary tract infection and urine samples of patients with reproductive culture results were evaluated retrospectively.

A total of 191 E. coli strains isolated from urine cultures which were processed between January 2008 and December 2008 in the clinical laboratory, were included in the study. Identification of bacteria and antibiotic susceptibility tests were performed by disk diffusion and automated system. Of E. coli strains, 14.6% (n=28) were found positive for ESBL. The resistance rates of E. coli strains were found as follows; 12.4% for nitrofurantoin, 40% for trimethoprim/sulfamethoxazole (TMP-SMX), 19.8% for ciprofloxacin and 19.2% for ceftriaxon.

Empirical therapy should be based on local antimicrobial resistance monitoring in order to optimize the use of these drugs. (JAREM 2012; 2: 101-3)
