Genetic characterization of ESBL-producing and ciprofloxacin-resistant E. coli from Belgian broiler and pig farms

The increasing number of infections caused by Escherichia coli resistant to clinically important antibiotics is a global concern to both human and animal health. The overall levels of extended-spectrum beta-lactamase (ESBL) producing and ciprofloxacin-resistant (ciproR) E. coli in livestock are found to be high in Belgium. This cross-sectional study aimed to genotypically characterize and trace ESBL-and ciproR-E. coli of Belgian food-producing animals.
