Multidrug-Resistant Escherichia coli in Bovine Animals, Europe.

ABSTRACT

Of 150 Escherichia coli strains we cultured from specimens taken from cattle in Europe, 3 had elevated MICs against colistin. We assessed all 3 strains for the presence of the plasmid-mediated mcr-1 gene and identified 1 isolate as mcr-1-positive and co-resistant to ß-lactam, florfenicol, and fluoroquinolone antimicrobial compounds.
