FIG 5.

General phenotypic differences between EAEC strains during biofilm formation. (A) WT C227-11 (Stx⁺), ::qseC C227-11 (Stx⁺), qseC⁺ C227-11 (Stx⁺), and BA3826 (Stx^–) strains on 96-well polystyrene plate in the presence or absence of 1% α-methyl d-mannoside incubated for 24 h at 37°C. (B) Motility profile between E. coli strains compared to WT C227-11 (Stx⁺) plated on LB agar 0.3% and incubated at 37°C. Growth halos were measured 24 h after incubation. Statistical analysis was performed using a Student t test between each group or ANOVA. Error bars indicate the SD of the mean (**, P < 0.001; ***, P < 0.0001; ns, not significant).
