The C. jejuni CS isolate and the C. jejuni Turkey flgR mutant display greater resistance to sodium deoxycholate (DOC) than the C. jejuni Turkey isolate. The C. jejuni CS isolate (open bars), C. jejuni Turkey isolate (gray bars), and C. jejuni Turkey flgR mutant (black bars) were incubated in MH broth with 0.1%, 0.05%, 0.025%, and 0% sodium deoxycholate under microaerobic conditions for 48 h at 37°C with shaking. The y axis represents the optical density of bacterial culture relative to the growth achieved without deoxycholate (0% sodium deoxycholate). The error bars represent the standard deviations.
