Abstract
The effect of serum bactericidal antibody on colonization with NTHI was studied in 26 children. Serum bactericidal antibody did not prevent colonization with NTHI in the nasopharynx. Antibody was detected in 53% before, 91% during, and 100% after documented colonization. The log titer of antibody was significantly higher during (1.18 ± 0.56), p < 0.002; and after (1.31 ± 0.29), p > 0.001 compared to before colonization (0.49 ± 0.51). The roles of secretory IgA and normal nasopharyngeal flora in inhibiting pathogenic bacteria are discussed.
