Lung leukocytes were isolated from uninfected (week 0) or infected young and mature mice at weeks 1 and 2 postinfection. Cells were spun onto a glass slides, stained with Wright-Giemsa stain, and analyzed using a microscope. The absolute number of leukocyte subsets was calculated by multiplying the percentage by the total number of cells. Data are expressed as means ± standard error (n ≥ 4 mice/group/time point) and are representative of two independent experiments. Leukocyte numbers from young and mature mice were not statistically different from one another at any time point.
