Fig. 6

Lawn leaving behavior for N2, CB4856 and different mutants towards E. coli and P. aeruginosa. Results for: (a) E. coli OP50; and (b) P. aeruginosa strain PA14. The Y axis shows the proportion of escaped worms; the X axis shows the three time points at which leaving was scored (12 h, 24 h, and 48 h). The asterisk (*) denotes the treatments which differ significantly from N2, whereas the hash sign (#) indicates significant differences from CB4856. The dotted reference line shows a leaving proportion of 0.5. Error bars represent standard error of the mean. The raw data are provided in sheet 6 of Additional file 2; detailed statistical results in Additional file 12
