Abstract : In this study, we assessed the selective effect of colistin orally administered to healthy weaned piglets harbouring an intestinal mcr-1-positive Escherichia coli strain. Maximum recommended dose and a higher dose often used in European pig farms were given by gavage. No selection of the mcr-1-positive strain was observed in our controlled conditions whatever the dose. Further investigations in real farming conditions seem necessary.
