Background: Klebsiella pneumoniae is considered of the bacteria causing urinary tract infection and one of the opportunistic pathogens and cause of nosocomial infections. Outbreak of ESBL (broad-spectrum β-Lactamase) in the bacteria leads to the improvement of antibiotic resistance and mortality in patients.
Materials and Methods: This descriptive study in 2010 took 22 months. Bacteria were identified according to the microbiological methods and production of broad-spectrum β-Lactamase through screening and confirmatory tests.
Results: Based on the results, the frequency of Klebsiella pneumoniae in samples of inpatients and outpatients has been respectively 15% and 14%, and the frequency of broad-spectrum β-Lactamase in Klebsiella pneumoniae bacteria in samples of inpatients and outpatients has been respectively 64% and 22%.
Conclusion: The results indicated the prevalence of broad-spectrum β-Lactamase in isolated strains from comparison between inpatients and outpatients.
