Abstract (EN): The mcr-1 gene spread is worldwide recognized as a public health threat at multidrug-resistant infections therapy level. Here, we report for the first time, to the best of our knowledge, the detection of the globally distributed IncX4 plasmid carrying mcr-1 (mcr-1/IncX4) in Escherichia coli isolated from a wild mammal in Portugal and Europe. This plasmid was found in a ST533 E. coli isolate with a multidrug-resistant profile, virulence potential, and possibly phylogenetically related to human isolates. Our work contributes to highlight the importance of antimicrobial resistance (AMR) surveillance in wildlife, an important compartment of the whole ecosystem often overlooked in the fight against AMR.
