Abstract

Purpose:
Urinary tract infections are the second most common human infection by family of the Enterobacteriaceae, particularly Escherichia coli. According to the increasing antibiotic resistance among strains of E. coli, the purpose of this study was to determine the current pattern and also to investigate changes in the antibiotic resistance patterns of Escherichia coli strains isolated from urinary tract infections in outpatients referring to Nabi-akram hospital in Zahedan city during the past years.
Methods:
This descriptive study was conductedon 87 cases of E. coli isolated from patients with urinary tract infections in a hospital in the city of Zahedan. The drug sensitivity test for antibiotics: imipenem (IPM), gentamicin (GM), ceftazidime (CAZ), nalidixic acid (NA), amikacin (AN), nitrofurantoin (FM) and cotrimoxazole (SXT) for isolates of Escherichia coli was performed.
Results:
Of a total of 87 samples, 70.2% of isolates were women and 29.8% of isolates were isolated from men. Patients' age range was of 12-45 years. The popular resistance to antibiotics: cotrimoxazole (66.6%), nalidixic acid (63%), ceftazidime (44.8%), nitrofurantoin (26.1%), amikacin (19.5%), gentamicin (13.7%) and imipenem (4.5%) were evaluated.
Conclusion:
Based on the results of this study, the antibiotics imipenem and cotrimoxazole had the highest resistance and susceptibility, respectively. Therefore, it is recommended to stop the administration of cotrimoxazole antibiotics to treat urinary tract infections and use Imipenem.
