Figure 2From: A eukaryotic-type signalling system of Pseudomonas aeruginosa contributes to oxidative stress resistance, intracellular survival and virulenceSurvival of P. aeruginosa PAO1 and Δ ppp A- ppk A strains upon exposure to environmental stresses. (A) Oxidative stress with 1 to 50 mM H 2 O 2 . The differences between the mutant and its parental wild-type strain are statistically significant (P < 0.05) for all H2O2 concentrations. The standard errors of the means from three independent assays are shown. (B) Hyperosmotic stress with 1.3 to 2 M NaCl. The standard errors of the means from three independent assays are shown. The differences between the mutant and its parental wild-type strain are statistically significant (P < 0.05) for 1.3 and 1.6 M NaCl. An asterisk indicates a significant difference.Back to article page
