RESUMO

The aim of this study is to determine the resistance patterns of bacteria causing nosocomial infections. The outcome of this resistance was followed for 3 years. This study was carried out during 2000 to 2002 at a university hospital in Turkey. The resistance patterns of 570 bacteria [390 Gram-negative, 180 Gram-positive] against meropenem, imipenem, ceftazidime, cefotaxime, cefepime, piperacillin/tazobactam, ciprofloxacin and tobramycin were investigated using the E-test. Extended-spectrum beta-lactamase [ESBL] production was determined using ceftazidime and ceftazidime/clavulanic acid E-test strips. Meropenem was the most effective antibiotic against Gram-negative organisms [89.0%]; this was followed by imipenem [87.2%] and piperacillin/tazobactam [66.4%]. The most active antibiotic against Gram-positive bacteria was imipenem [87.2%] and this was followed by piperacillin/tazobactam [81.7%] and meropenem [77.8%]. The rates of production of ESBL by Escherichia coli were 20.9%, Klebsiella pneumoniae 50% and Serratia marcescens were 46.7%. Extended-spectrum beta-lactamase production increased each year [21.7%, 22.1% and 45.5%]. All of the ESBL producing isolates were sensitive to meropenem and 98.5% sensitive to imipenem. AmpC beta-lactamase was produced by 20.9% of the Enterobacter species spp, Citrobacter spp. and Serratia marcescens. All of these were sensitive to meropenem and 77.8% to imipenem and ciprofloxacin. Multi-drug resistance rates in Acinetobacter spp were 45.4% and 37.7% in Pseudomonas aeruginosa isolates. As in the entire world, resistance to antibiotics is a serious problem in our country. Solving of this problem depends primarily on prevention of the development of resistance
