  • Introduction: Bacterial infectious diseases can affect the quantity and quality of life. Escherichia coli are the most common bacteria that cause urinary tract infections. Due to the various mechanisms of antibiotic resistance, treatment of these infections is difficult. Therefore, choosing the right antibiotic has an effective role in controlling and improving the infection. Therefore, the aim of this study was to determine the frequency and pattern of antibiotic resistance in Escherichia coli and Klebsiella pneumoniae strains isolated from patients admitted to Khorshid Hospital in Isfahan.
  • Methods: This cross-sectional study was performed on 30 samples of patients admitted to Khorshid Hospital in the first 6 months of 1398. The strains were identified and identified using biochemical tests and differential culture media. The pattern of antibiotic resistance of the studied strains was investigated by disk diffusion (Kirby-Bauer). Chi-square test was used to analyze the data.
  • Results: Thirty samples were positive for Escherichia coli and Klebsiella pneumoniae. Of these, 50% of Escherichia coli strains and 50% of Klebsiella pneumoniae strains were isolated. The highest and lowest antibiotic resistance in Escherichia coli were Cotrimoxazole and Nitrofurantoin, respectively. Klebsiella pneumoniae strains had the highest resistance to Nitrofurantoin and the lowest resistance to Gentamicin.
  • Conclusion: Nitrofurantoin, Ciprofloxacin are recommended for the initial treatment of urinary tract infections.
