pigs from one batch in the nursery had been randomly divided into two groups following weaning: control (C) and supplemented (S). The control group received a standard commercial feed containing chlortetracycline and penicillin G and the supplemented group had received the same feed but also containing 2% clinoptilolite. None of the pigs had been treated with other antimicrobials, including ceftiofur, during the experiment.

138 of the 408 blaCMY-2-positive isolates from the previous study were selected to represent sampling days and groups. ontrol (n = 66) and supplemented (n = 72) groups at days 2, 7, 14 and 28 after weaning. No blaCMY-2-positive E. coli isolate had been detected at day 0.101 blaCMY-2-negative E. coli isolates were recovered from the control (n = 53) and supplemented (n = 48) groups representing all sampling days (0, 2, 7, 14 and 28).
