We investigated whether the therapeutic usage of aminopenicillins selects antimicrobial resistance in porcine C. coli isolates. Seven Finnish farrowing farms that treat piglets or sows with injectable aminopenicillins were selected for this study. Aminopenicillins were administered for the treatment of diarrhea or MMA (mastitis, metritis, agalactia) syndrome at 15mg/kg intramuscularly for 3–5 days. Twenty-six animals (seven sows and 19 piglets) received aminopenicillin therapy. Susceptibilities to ampicillin, ciprofloxacin, and erythromycin were determined either with the VetMIC or the agar dilution method (CLSI, 2002).

Individual faecal samples were taken from the rectum with Probact transport swabs ( Juntunen et al., 2010).
