Feeding rates of tph-1(mg280) on HB101 (A) and JU54 (B) after a 7- to 8-hr interval from training the animals on one or the other bacterium. Data shown as mean ± SEM, n.s., not significant (p≥0.05), unpaired t-test and Mann–Whitney U test (two-tailed). The number of animals tested (n ≥ 3 independent assays per each group) is shown in parentheses.
