Abstract Background There are few epidemiological or molecular data on Escherichia coli (E. coli) strains resistant to fosfomycin. In this study, we described the occurrence and characterization of fosfomycin-resistant uropathogenic E. coli (UPEC) isolated from children. Materials and methods This study was carried out on 96 E. coli isolates obtained from children with urinary tract infections. Two methods were performed to detect fosfomycin resistance: The agar dilution method and the rapid fosfomycin test. The disc diffusion method was done to detect the antimicrobial susceptibility pattern of all isolates. The phylogenetic grouping of all isolates was done according to the modified Clermont method. Conventional PCR was performed to detect plasmid-mediated fosfomycin-resistant genes (fos genes) and the bla CTX−M gene. Results Analyses of data were performed by SPSS software. A high percentage of fosfomycin resistance (37/96; 38.5%) was reported among UPEC isolates. The fosfomycin-resistant strains showed a higher resistance rate than fosfomycin-susceptible isolates to different antibiotics. E group (62.2%) was the most predominant phylogenetic group among the fosfomycin-resistant UPEC isolates, followed by Group B2 (21.6%) and group D (13.5%). The fos genes were detected in 21 isolates with the fosA3 gene as the most frequent, which was detected in 11 isolates followed by fosA (8), fosC2 (4), fosA4(1), and fosA5(1) genes. Conclusion This is the first report of a high prevalence of plasmid-mediated fosfomycin-resistant UPEC in Egypt. All of these isolates were multidrug-resistant to the tested antibiotics. Close monitoring of such strains is mandatory to prevent widespread dissemination of the genes code for antibiotic resistance. |
