FIG. 4.

Comparison of the clearance in P5 peptide-specific antibody-responding and -nonresponding rats. The percent clearance was calculated for individual animals as described in the legend for Fig. 3. The mean of the nonimmune group was given the value of 0% clearance. The animals with peptide-specific serum IgG are indicated with stars, and the means of each group are indicated by bars. Notably, the animal producing MVF/L1A-specific antibody had more viable NTHi in the BAL fluid than the nonimmune animals.
