This study explored the prevalence and persistence of acquired antimicrobial resistance in Escherichia coli and Enterococcus faecium from healthy broilers. In 32 broiler farms, cloacal samples were taken during two production rounds, with one production round in between. For 10 of the sampled flocks, samples from the carcasses at the slaughterhouse were also collected. For E. coli, high levels of resistance were found for ampicillin, nalidixic acid, streptomycin, tetracycline, and the combination of trimethoprim and sulfonamide. Over 58% of all the isolates showed resistance to four or more…
