Immunohistochemical analysis of the lung sections in mice infected with recombinant Mycobacterium smegmatis. Paraffin-embedded sections of lung tissues were examined by immunohistochemistry with cleaved caspase-3 (ASP175) antibody {cleaved caspase-3 stained as brown pigment (blue arrows) [Rv0888NS/MS, D438A/MS, and polysialic acid (PLA)]} counterstained with hematoxylin. Images are representative of one of three independent experiments with three lung sections per group. Scale bars = 50 µm.
