Growth curves of C. jejuni strains. C. jejuni NCTC 11168 and its derivatives were initially adjusted to an optical density at 600 nm (OD600) of 0.08, after which they were grown in MH broth under microaerophilic conditions with shaking at 42 °C, with 200 μl of samples were withdrawn at designated time point to examine growth. The wild-type strain (red circle), the flhF mutant strain (blue triangle) and the flhF complemented strain (green cross) are represented by each sample. The data are presented as the means ± standard deviation (SD) from three independent experiments
