Experimental design. Four groups of rats were used as recipients of different treatments: (C) controls; (A) ATB intake during 3 d; (T) transplantation; (AT) 3-d ATB intake followed by transplantation. The cecal content of four donor rats was pooled and transplanted to a recipient rat once by gavage. Fecal samples of all rats were collected at different time points, day 0 (D0), day 3 (D3), month 1 (M1), and month 3 (M3).
