Transcriptional response of motility and pathogenicity island genes on entry into water. Fold‐change (log2) in expression of flagella and chemotaxis genes at 0.5 h (30 min), 6 h (6 h) and 24 h (24 h) after entry into water, are indicated at each time point relative to expression during culture in LB broth (0 on the y‐axis) for, class 1 (A), class 2 (B), class 2 and 3 (C) and class 3 (D) promoters, and for SPI‐1 (E) and SPI‐2 (F) encoded genes.
