Histopathology of mucicarmine-stained Tgɛ26 lungs infected with the Δgcs1 strain and treated with empty liposomes. Panels A and B show lung fields from two different mice at day 16 of infection. The filled arrowheads indicate Δgcs1 cells within macrophages, whereas the open arrowheads indicate extracellular Δgcs1 cells. Bars = 50 μm (left panels) and 10 μm (right panels).
