ABSTRACT

Introduction: The increment of antimicrobial resistance in enterobacterium stumps is a worldwide problem, particularly Escherichia coli and Klebsiella pneumoniae, due to the antibiotic therapies abuse; becoming a great challenge for medicine and technological improvements.
Objective: To determine the extended spectrum betalactamasas (ESBL) frequency in Escherichia coli and Klebsiella pneumoniae isolations in patient with urinary tract infection (UTI).
Method: Descriptive and observational study that it included from February 2011 through July 2013 period. The sample was 150 positive urocultivos about patients assisted in the Hospital's Urology service; 73 of them were confirmed the Escherichia coli and Klebsiella pneumoniae BLEE producers presence.
Results: The studied showed that Escherichia coli and Klebsiella pneumoniae stumps constituted the higher isolation percentage found in patients with UTI translated to the Urology service. ESBL and acetiltransferas (6') AAC´ enzymes, were the bigger responsible for the Escherichia coli and the Klebsiella pneumoniae stumps antimicrobial resistance in the patients studied. The previous use of antibiotics and the renal lithiasis were the most common risk factors present in the ESBL producer’s bacterium isolations.
Conclusions: Antimicrobial resistance is a nowadays problem that requires special attention by clinical physicians, microbiologists and other professionals in order to diagnose and treat the infections; that is why it is necessary to know that Escherichia coli and the Klebsiella pneumoniae are the most frequent ESBL producer’s stumps in the patients remitted from the Urology service.
