FIG 5.

Immune cell infiltration of the genital tract during C. muridarum primary infection in CD4-depleted and nondepleted IFN-γ^−/− and μMT mice. Whole genital tracts were collected, prepared, and stained as described for Fig. 1 in depleted and nondepleted naive IFN-γ^−/− and μMT mice (A) and at 7 days (B) and 21 days (C) following primary intravaginal infection. Data represent the mean number of positive-staining cells per genital tract ± SD of nondepleted IFN-γ^−/− (n = 9) and μMT (n = 9) mice and of depleted IFN-γ^−/− (n = 6) and μMT (n = 6) mice, respectively.
