Multidrug-resistant high-risk clonal *Escherichia coli* lineages occur along an antibiotic residue gradient in the Baltic Sea

P. Lübcke, S. E. Heiden, et al.

This groundbreaking study conducted by Phillip Lübcke and colleagues highlights the alarming presence of ESBL-producing *E. coli* in northeastern Germany's surface water. The research delves into antibiotic resistance, heavy metal tolerance, and potential reservoirs for these bacteria in the Baltic Sea, revealing critical insights about our water systems and public health.

Abstract
This study examined the presence of ESBL-producing *E. coli* in surface water in northeastern Germany, analyzing their AMR, heavy metal tolerance, biofilm formation, and plasmids, alongside antibiotic residue quantification. The analysis identified 30 ESBL-producing *E. coli* isolates, some linked to high-risk clonal lineages. Antibiotic residues were detected, though at lower concentrations than in wastewater. The Baltic Sea surface water may act as a reservoir for ESBL-producing *E. coli* and relevant antibiotics.
