RESUMO

This study evaluated the relationship between florfenicol resistance and flo genotypes in 1,987 Escherichia coli isolates from cattle. The flo gene was detected in 164 isolates, all of which expressed resistance to florfenicol at MICs of ≥256 μg/ml. The florfenicol MICs for all isolates that lacked flo were ≤16 μg/ml.
