ABSTRACT: Introduction: The increasing incidence of urinary tract infections (UTIs) caused by multidrug-resistant organisms represents a pressing global health challenge. The current study aims to investigate longitudinal trends in antibiotic resistance among Enterobacteriaceae isolated from urine samples in Burkina Faso. Methods: A retrospective study was conducted at three medical laboratories in Burkina Faso over 6 years (January 1, 2017, to December 31, 2022). Data extracted from laboratory registers included patient demographics (age and sex), bacterial species identified, and antimicrobial susceptibility testing results. Results: Data from 5,310 positive patient urine cultures were extracted and analyzed in this study. Escherichia coli (67.12%) and Klebsiella pneumoniae (25.99%) were the predominant species. There was a marked increase in resistance to key antibiotic classes: amoxicillin resistance rose from 50.6% to 92.7%, ciprofloxacin from 43.2% to 60.2%, and third-generation cephalosporins from 36.0% to 53.4%. Multidrug resistance (MDR) prevalence increased from 80.9% to 92.1% over the study period. Conclusions: The study highlights a critical escalation in antimicrobial resistance among uropathogens in Burkina Faso. Incorporating local resistance data into empirical treatment guidelines and investing in diagnostic stewardship are essential to preserve treatment efficacy and prevent the spread of resistant strains.
