In-feed bacitracin methylene disalicylate alters microbiota function and increases antibiotic resistance in a dose-dependent manner

Paul O Oladele, Carmen L. Wickware, Julian Trachsel…·Timothy A. Johnson

This study shows that therapeutic doses of bacitracin methylene disalicylate increase antibiotic resistance genes and alter microbiota metabolism in turkeys, while subtherapeutic doses have temporary effects.
