Survival and colony formation of C. jejuni exposed to elevated growth temperatures or osmotic stress. The 81-176 wt, mutant (ΔracR and ΔracS), and complemented (ΔracRC) strains were diluted to an OD600 of 0.1 and spot plated onto solid medium at a serial dilution ranging from 100 to 10−5 (denoted by the vertical wedge). Images were captured after 48 h of incubation at the indicated temperatures on unsupplemented MH plates (A) or on MH plates supplemented with 0.8% NaCl at the indicated temperatures (B) and are representative of three independent experiments.
