Activity of the M. tuberculosis ppa promoter in macrophages. Murine bone marrow-derived macrophages were infected with A) BCG/pJIN6 (gfp controlled by ppa promoter) or B) BCG/pJIN10 (gfp controlled by sigE promoter). After 6 days, macrophages were lysed and the fluorescence of recovered bacteria assessed by flow cytometry (grey histogram) and compared to the fluorescence of the initial inoculum (white histogram).
