Evaluation of the Prevalence of Urinary Tract Infections and the Sensitivity of the Micro-organisms Involved, to Antibiotics used in Behbood Hospital (Tabriz) in the Years 2011-2014

Background and Objectives: Urinary tract infection (UTI) is the presence of microbial pathogens within the urinary tract and is one of the most common infections in both patients admitted in the hospitals and outpatients. Unfortunately, in recent years, antibiotic resistance has become a major problem in many countries. The present study aimed to evaluate the antibiotic sensitivity of urinary tract pathogens in Behbood Hospital (Tabriz) in the years 2011-2014. Materials and Methods: This study is a retrospective (existing data study), based on the defined objectives (examining the prevalence of urinary infection and the sensitivity and resistance of the pathogens to antibiotics). Gender and age of patients, type of isolated bacteria in urine culture, susceptibility and resistance of these bacteria to current antibiotics were studied in a four year period from April 2011 to the end of March 2014. Results: The most prevalent cause of UTI was Escherichia coli (E. coli) (77%), in all age groups and both gender. E. coli sepsis was highly sensitive to nalidixic acid (76.2%), trimetoprim (52.4%) and ciprofloxacin (40.8%), with the greatest resistance to nitrofurantoin (92.2%). Conclusion: the study results indicate that E. coli was the first responsible pathogen in the culture of UTI. In several countries, the need for local population-specific surveillance to guide empirical therapy for UTI in patients is emphasized.
