Fig. 5From: mRNA-Seq reveals the quorum sensing system luxS gene contributes to the environmental fitness of Streptococcus suis type 2Survival rates of SS2 strains under oxidative stress. The SS2 strains were inoculated at medium containing 58.8 mmol/L H2O2, and the survival of each strain was measured at indicated time. The survival rate of mutant strain ΔluxS was higher than those of the wild-type strain, CΔluxS and luxS+ at 1 h, 2 h, 3 h or 4 h. *, significantly different at p < 0.05; **, significantly different at p < 0.01; ***, significantly different at p < 0.001Back to article page
