<i>Mtb</i> infection resulted in a decrease in macrophage and CD4+ T cell number.

<p>Granuloma samples were harvested and host cells were analyzed for expression of cellular markers by flow cytometry as described in methods. Graphs depict 1 wk and 2 wk post-infection profiles of uninfected and infected granuloma samples for (<b>A</b>) CD4+3+ T cells, (<b>B</b>) CD8+3+ T cells, (<b>C</b>) CD19+ B cells, (<b>D</b>) CD4+25+ T cells, (<b>E</b>) CD14+11c+ macrophages. Data are represented as mean +/− SEM from 3 experiments.* p<0.05 for CD4+25+ cells at 2 wk time point for 1∶0.1 MOI-infected group compared to the uninfected group.
