Efficacy of a competitive exclusion culture against extended-spectrum β-lactamaseproducing Escherichia coli strains in broilers using a seeder bird model

Administration of a competitive exclusion culture (CE culture) has the potential to induce protective effects in very young chicks against caecal colonisation by EEC (= extended-spectrum β-lactamases [ESBL] and AmpC-type [AmpC] beta-lactamases producing Escherichia coli).
