Live E. faecalis perturbs defecation cycle length in C. elegans. (A) Sequential defecation cycle lengths (time between consecutive contractions of the posterior body wall muscle) in wild-type C. elegans fed on E. coli, E. faecalis, or E. faecium. (B) Defecation cycle lengths in L4 worms fed E. coli, E. faecalis, or E. faecium, either live or heat-killed, for 24 hours. Mean defecation cycle lengths are indicated with horizontal bars. Results are representative of 3 independent assays. Relevant statistically significant differences are indicated with a bracket. Statistical significance was calculated using an unpaired t-test and the Holm-Sidak method for multiple comparison correction.
