Figure 2. IL-22 is required for protection during chronic stages of Mtb HN878 infection.

Figure 2

Il22-/- and B6 mice were aerosol infected with (a) ∼100 CFU, or (b) ∼500 CFU, of Mtb HN878. Bacterial burden in the lungs and spleens was assessed by plating after (a,b) 30 and 100 days post infection (p.i),. Error bars represent means ± SD n = 5-14 mice for each time point. *P ≤ 0.05, **P ≤ 0.01, ***P ≤ 0.001 by (a,b) Student's t test.
