  1. Proportion of herds with E. coli resistant to trimethoprim-sulphonamide in relation to proportion of sows receiving post-farrowing antibiotic treatments. Data for 135 isolates from the 83 herds which submitted questionnaires on farm use of antibiotics. Higher proportion of post-farrowing treatments were associated with higher occurrence of antimicrobial resistance in E. coli from piglets with diarrhoea
