Prevalence of Klebsiella pneumoniae ESBLs Producer Strains in Hospitalized and Community Acquired Urinary Tract Infections

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. 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. 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%. The results indicated the prevalence of broad-spectrum β-Lactamase in isolated strains from comparison between inpatients and outpatients.
