Background & Aims: Escherichia coli, a gram-negative bacillus, is one of the most common pathogens causing urinary tract infections. Several studies have demonstrated that the antibiotic fosfomycin has a significant inhibitory effect on Gram-negative pathogens, including Escherichia coli, by inhibiting peptidoglycan production. This study aimed to better understand the effect of fosfomycin against multidrug-resistant Escherichia coli causing urinary tract infections.
Materials and Methods: In this epidemiologic-descriptive study, 90 Escherichia coli isolates were collected between October 1401 and October 1402 from urine samples of teaching hospitals in Qazvin city. ESBL- and AmpC-producing strains were identified using the phenotypic method. Data were evaluated and analyzed using SPSS software version 2022 with a significance level of less than 0.05.
Results: Among the 90 isolates of Escherichia coli, the highest antibiotic resistance was observed for ampicillin (96.6%), cefotaxime (90%), and ceftazidime (84.4%), while the highest susceptibility was related to the antibiotics fosfomycin (98.9%), meropenem (98.8%), gentamicin (88.8%), and nitrofurantoin (84.4%).
Conclusion: With the increase in antibiotic resistance and the spread of strains producing beta-lactamase enzymes, the treatment of infections caused by these strains has become a serious problem. In this study, the susceptibility of Escherichia coli isolates that produce broad-spectrum beta-lactamases and are resistant to multiple drugs to fosfomycin was investigated. It was found that 89 (98.9%) isolates were sensitive to fosfomycin, indicating that fosfomycin is an effective antibiotic against ESBL isolates in Iran.
