Kinetic in BCG-induced mycobacterial growth inhibition. Groups of mice were immunised with a single dose BCG or given Tris buffer (Placebo) three times s.c. with 2-week intervals. In different immunisation experiments, splenocytes were isolated 1 week, 5 weeks or 29 weeks after BCG immunisation and used in MGIA. Delta log10 CFU values represent the BCG-induced mycobacterial growth inhibition and were calculated by subtracting the individual log10 CFU values in the immunised BCG groups from the mean of the respective placebo group. Solid lines represent the mean delta log10 CFU of 4, 8 and 4 mice, for 1 week, 5 weeks or 29 weeks, respectively, measured in duplicates. t-test between the BCG group and the respective placebo group. *p < 0.05; ****p < 0.0001.
