Global Clones of Escherichia coli CTX-M-15/ST10 and CTX-M-65/ ST683 Isolated from Brazilian Recreational Freshwater.

ABSTRACT: The emergence of antimicrobial resistance (AMR) poses a critical global health threat, underscoring the interconnectedness of human, animal, and environmental health within the One Health framework. This study describes two multidrug-resistant (MDR) extended-spectrum beta-lactamase (ESBL)-producing Escherichia coli strains, classified as critical priority bacteria by the World Health Organization, identified in recreational freshwater in Brazil. A cross-sectional study was conducted to investigate the presence of ESBL-producing Enterobacterales in water samples from a river in a touristic Brazilian city, including the waterfall, stream, and areas outside the city center. Bacteria were cultured and isolated on MacConkey agar supplemented with ceftriaxone, identified by MALDI-TOF, and antimi
