FIG. 9.

Levels of inflammatory cells in BAL samples from BALB/c mice in which neutrophils were depleted with the antibody RB6 (RB6) and BALB/c wild-type mice (WT) both depleted of CD4⁺ lymphocytes and inoculated with 10⁷ Pneumocystis organisms, as well as those in samples from nondepleted, noninfected BALB/c control mice (CON). Mice were sampled at 15, 28, and 35 days postinoculation. Values are means ± SD. n = 5; *, P < 0.05; **, P < 0.01 (comparing RB6 to WT mice). Results shown are representative of those from two independent experiments.
