Figure 6

The pathogenicity of wild-type and conditional mutant MTB strains. The wild-type MTB H37Rv bacteria showed the highest infection capacity (approximately 10 bacteria per macrophage) (A), while the capacity of the mutant to infect macrophages was gradually increased with the concentration of pristinamycin and the period of induction (B). The experiments were repeated for three times, and results were expressed as mean ± SD. Results were compared using one-way ANOVA method (*** p < 0.001).
