Immunization with whole-cell pertussis vaccines (WCV) containing
heat-killed Bordetella pertussis cells and with acellular vaccines containing genetically or chemically detoxified pertussis toxin (PT) in combination with filamentous hemagglutinin (FHA), pertactin (Prn), or fimbriae confers protection in humans and animals
against B. pertussis infection. In an earlier study we demonstrated that FHA is involved in the adherence of these bacteria to
human bronchial epithelial cells. In the present study we investigated whether mouse antibodies directed against B. pertussis FHA,
PTg, Prn, and fimbriae, or against two other surface molecules,
lipopolysaccharide (LPS) and the 40-kDa outer membrane porin protein
(OMP), that are not involved in bacterial adherence, were able to block
adherence of B. pertussis and B. parapertussis
to human bronchial epithelial cells. All antibodies studied inhibited
the adherence of B. pertussis to these epithelial cells and
were equally effective in this respect. Only antibodies against LPS and
40-kDa OMP affected the adherence of B. parapertussis to
epithelial cells. We conclude that antibodies which recognize surface
structures on B. pertussis or on B. parapertussis can inhibit adherence of the bacteria to bronchial
epithelial cells, irrespective whether these structures play a role in
adherence of the bacteria to these cells.
