Figure 3From: Roles of RpoN in the resistance of Campylobacter jejuni under various stress conditionsEffect of the rpoN mutation on acid stress resistance. (A) Growth of the rpoN mutant under different pH conditions was examined by dotting 10 μl of serially-diluted bacterial cultures. The results are representative of three independent experiments with similar results. (B) Viable cell counts on MH agar with different pH after 24 hr incubation. The % viability is expressed as mean ± standard deviation of three independent experiments. ***: P < 0.001; the significance of results was statistically analyzed by one-way ANOVA using Prism software (version 5.01; GraphPad Software Inc.).Back to article page
