Feeding rates of ser-4(ok512); mod-1(ok103) on HB101 (A) and DA1878 (B) after a 7- to 8-hr interval from training the animals on one or the other bacterium. Like wild type worms, ser-4(ok512); mod-1(ok103) show increased feeding response on familiar food compared to novel food. Data shown as mean ± SEM, unpaired t-test and Mann–Whitney U test (two-tailed). The number of animals tested (n ≥ 3 independent assays per group) is shown in parentheses.
