blaNDM-5-positive and mcr-9-carrying Escherichia coli lineages in wild Andean condors feeding at landfills in South America
and, in two isolates, mcr-9. These isolates belonged to sequence types 46, 345, 744, and 2973 and carried broad resistomes to β-lactams, aminoglycosides, fluoroquinolones, sulfonamides, trimethoprim, phenicols, and tetracyclines, together with genes associated with disinfectants and heavy metals. These findings highlight exposure of wild Andean condors to clinically relevant carbapenem-resistant E. coli in landfill-associated environments and support the need for preventive measures to reduce wildlife contact with anthropogenic waste.
