Colonization levels in the upper airways of mice inoculated with NTHi. (A) Mice were exposed to CS or air as indicated and intranasally inoculated with NTHi. Colonization densities were determined by quantitative cultures of upper airway lavages 24 hours postinoculation. Data are shown as mean ± SEM. Bars indicate significant differences of *p < 0.05, n ≥ 5 per group. (B) NTHi are shown in nasal tissue by immunohistochemistry (red staining). Scale bar, 100 μm.
