Molecular characterization of mcr-1.1-harboring multidrug-resistant Escherichia coli isolates from chicken in the United Arab Emirates: implications for one health surveillance

Our findings highlight the complex interaction between plasmid-mediated colistin resistance, AMR, and virulence traits in <i>E. coli</i> from the food chain. The genetic and plasmid similarities between <i>mcr-1.1-</i>producing isolates across multiple countries emphasize the risk of possible dissemination and the potential risk of cross-border dissemination through globally traded food products. This study underscores the need for regional and global surveillance and control measures to mitigate the spread of this multidrug-resistant pathogen.
