Effect of oxidative stress on the survival of C. jejuni NCTC 11168 (triangle a) and C. jejuni Bf (circle b) strains cultured in MAC, and C. jejuni Bf in AAC (square c) after exposure to different concentrations of H2O2 (A), and paraquat (B) for 1 h at 42 °C. The number of colony-forming units was determined by plating serial dilutions on Karmali agar using the microdroplet technique followed by incubation at 42 °C for 24 h in MAC. The viability of oxidative stress was determined by inoculating 10 µL of bacterial suspension on Karmali agar plates after exposure to different concentrations of H2O2 and paraquat followed by incubation at 42 °C for 24 h in MAC. Plotted points are the mean measurements from three independent experiments. Error bars represent standard deviations, although they are too small to be visible in most cases. *Statistically significant difference between the strains in each condition tested (P < 0.05)
