(A) Experimental design for the feeding assay. Coding is as in Figure 1A. Each condition is coded by three letters representing the cultivation, training and test food in order. (B)–(E) feeding rates of wild-type worms on HB101 (B and D) And DA1878 (C and E) 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), *p<0.05, **p<0.01, ***p<0.001, one-way ANOVA, post hoc Tukey test. The number of animals tested (n ≥ 3 independent assays per each group) is shown in parenthesis.
