Diversity of ESBL-producing E. coli in various water and sediment types.

ABSTRACT: Antimicrobial resistance is a major global health threat, and aquatic ecosystems serve as critical interfaces between human activity and the environment, providing reservoirs and pathways for the spread of resistant bacteria. In this study, we investigated the prevalence and diversity of ESBL-producing Escherichia coli across multiple aquatic environments in Slovenia by analysing water, sediment, and wastewater treatment plant (WWTP) influent samples collected between June 2023 and April 2024. ESBL-producing E. coli was detected in 93% of WWTP influents, 61% of water, and 35% of sediment samples. From 315 positive samples, 564 isolates were subjected to whole genome sequencing. In total, 134 MLST-sequence types (STs) were identified, with globally prevalent lineages (ST131, ST38, ST10, ST6
