Figure 6. Morphometric analysis of lung parenchyma from BALB/c mice immunized by intravenous (A) or subcutaneous (B) injection. Mice were infected with Mycobacterium tuberculosis and treated with transfected cells as described in Material and Methods. We performed morphometric analysis of lung histology sections. Data represent means ± SD percent of the pulmonary area affected by inflammation of 5 mice per group. Results are representative of 2 experiments. Mφ = macrophages.
