Fig. 4: Immune cell distribution in the lungs after Mtb-AG or SC infection.

Lung cells (a, c) or tissue sections (b, d) from Mtb-SC or Mtb-AG infected rabbits at 2 and 4 weeks were stained with specific antibodies against. a CD11b, b IBA1 (macrophages), c CD4, and d CD8. Stained lung cells were analyzed by flow cytometry and stained lung sections were analyzed microscopically, and cells positive for the markers were counted manually in 40 random fields from each animal. n = 3 rabbits per group. Data were analyzed by Mann–Whitney U Test.
