  Introduction and Objectives: Escherichia coli and Klebsiella pneumoniae are the most agent of urinary tract infection (UTI) and prevalence Extended-Spectrum Beta-lactamase (ESBLs) in these bacteria due to spread of antibiotic resistance and mortality and morbidity in patients. The best manner for control of ESBLs in bacteria, are inhibition of spread these bacteria and use of standard method for recognizes ESBLs producer strains. Subject of this study was comparison frequency of ESBLs in Escherichia coli and Klebsiella pneumonia strain in UTI acquired patients with phenotypic test. Materials and Methods: This cross-sectional search was performed in Azzahra and Shariaty hospitals during of 2008-2009 years in Esfahan, according to statistical formula randomly selected 91 samples from urinary infections. Bacterial identification was performed with microbiological methods, ESBLs production was performed with screening and confirmatory test and survey antibiotics resistant pattern was performed with Kirby method. Results: Frequence of ESBLs in E.coli and K.pneumoniae strains was respectively 47.97% and 41.66% .According to antibiogram result respectively 59.2%, 54.9%, 30.3%, 27.8%, 19.5% and 16.7% of E.coli strains were resistant into Co-Trimoxazole, Nalidixic acid, Ciprofloxacin, Gentamicin, Ceftazidime and Nitrofurantoin and respectively 75%, 50%, 40%, 44.5%,37.5%, 37.5%, 22.3% and 0% of K.pneumoniae strains were resistant into Ampicillin, Co-Trimoxazole, Nitrofurantoin, Ceftazidime, Amikacin, Cephotaxime, Imipenem and Ciprofloxacin. Conclusion: The result showed high frequence of ESBLs, so  antibiotic resistant in isolated bacteria from hospitalized into out patience's that represent high spread  antibiotic resistant strains in hospitals.
