Activation of the σE pathway in AIEC strain LF82 during the biofilm formation process. Shown is the n-fold variation of rpoE mRNA levels in wild-type strain LF82 during biofilm formation (4, 16, and 24 h) relative to that of the wild-type strain grown for 4 h in classic medium. 16S rRNA levels were measured as controls. Data are the mean ± the SEM of three separate experiments. *, P < 0.05; **, P < 0.01.
