Background: The resistance of E. coli isolates to fluoroquinolone is a significant challenge to antibiotic treatment and infection control policies. A significant increase of ciprofloxacin-resistant E. coli has occurred during last years, indicating the need for further analysis. Objective: The current study was aimed to detect quinolone-resistance in multi-drug resistant E. coli isolates that were recovered from patients with urinary tract infection in the Urology and Nephrology center of El-Mansoura University, Egypt. Methods: The clinical uropathogenic specimens collected were studied. Identification and antimicrobial susceptibility testing were done using VITEK 2. Minimum inhibitory concentrations (MICs) of different quinolones were determined for fluroquinolone resistance (FQ-resistant) isolates. Also, they were screened for the presence of the plasmid mediated quinolone resistance (PMQR) qnrA, qnrB and qnrS genes by polymerase chain reaction (PCR) techniques. Results: In the present study, 100 (32.7%) E. coli of 305 uropathogenic specimens were tested. The patients involved in this study included both genders, females (76%) were the most affected group of patients as compared to males (24%). The quinolones resistance rate was 30% of the isolated E. coli samples. The detected genes for the quinolone's resistance samples were: 14 (46.6%) qnrB, 13 (43.3%) qnrS and 2 (6.6%) qnrA. Conclusion: This study identified quinolone resistance (qnr) gene in uropathogenic E. coli in EGYPT. These finding which suggest a possible resistance to quinolone are of high interest for better management of patients and control of antimicrobial resistance in Egypt.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
