Background: Urinary tract infections (UTIs), primarily caused by Escherichia coli, pose a global health challenge owing to rising antimicrobial resistance (AMR), particularly carbapenem-resistant (Carb-RT) and extended-spectrum beta-lactamase (ESBL)-producing uropathogenic E. coli (UPEC). This study analyzed AMR trends, virulence determinants, and molecular epidemiology of UPEC isolates from community and hospital settings in Pakistan.

Antimicrobial resistance (AMR) poses a significant global health threat, primarily stemming from its misuse and overuse in both veterinary and public healthcare systems. The consequences of AMR are severe, leading to more severe infections, increased health protection costs, prolonged hospital stays, unresponsive treatments, and elevated fatality rates. The impact of AMR is direct and far-reaching, particularly affecting the Sustainable Development Goals (SDGs), underscoring the urgency for concerted global actions to achieve these objectives.

Antibiotic resistance (ABR) is a growing public health concern worldwide, and it is now regarded as a critical One Health issue. One Health's interconnected domains contribute to the emergence, evolution, and spread of antibiotic-resistant microorganisms on a local and global scale, which is a significant risk factor for global health. The persistence and spread of resistant microbial species, and the association of determinants at the human-animal-environment interface can alter microbial genomes, resulting in resistant superbugs in various niches.
