Escherichia coli ESBL-AmpC cattle Raw sequence reads
We demonstrated that MDR ExPEC are present in the normal microbiota of cattle (more frequently in calves) and that antimicrobial resistance genes spread through farms. These genes can persist over a 4-year period in the dairy cattle population through both plasmids and E. coli clones despite important changes in AMU following the implementation of a new restricting regulation.
