Abstract
The human bactericidal antibody response to the major outer membrane protein P2, of nontypeable Haemophilus influenzae was studied. P2 was isolated from two strains of nontypeable H. influenzae and coupled to affinity columns. Pooled normal human serum was subjected to affinity chromatography with the P2 columns and a control column. Reducing the titer of antibody to P2 resulted in reduced bactericidal activity of that serum for the organism. Immunopurified antibody to P2 from human serum was bactericidal for the homologous strain. The extent to which these bactericidal determinants on P2 are conserved among strains was investigated. Immunopurified antibodies to P2 of two epidemiologically unrelated isolates were bactericidal for four of six strains tested. We conclude that P2 is a target for human bactericidal antibody and that some of these determinants that are recognized by human bactericidal antibody are conserved among strains of nontypeable H. influenzae.
