Fig. 5: VapBC13 and VapBC26 are required for the survival of M. tuberculosis during oxidative stress conditions.

The transcript levels of vapB13 (A) and vapB26 (D) were measured in ΔvapC13 and ΔvapC26 strains, respectively, by quantitative real-time PCR using gene-specific primers. The data obtained was normalized to sigA and is shown as the mean ± SD of fold change obtained from three independent experiments. B, C, E, F The bacterial loads of various strains were determined after exposure to 5 mM H2O2 for either 24 h or 72 h. The data shown in these panels is the mean ± SD of data obtained from two independent experiments performed in duplicates. P values depicted on the graphs were assessed using one-way ANOVA. Source data is provided in Supplementary Data Set 4.
