title: Immune response to the B oligomer of pertussis toxin.
abstract: Immunization of mice with the B oligomer of pertussis toxin induced antibodies to the native toxin as measured by an enzyme-linked immunosorbent assay. These antibodies neutralized the ability of pertussis toxin to alter the morphology of Chinese hamster ovary cells. Furthermore, mice immunized with the B oligomer, when challenged with pertussis toxin, did not exhibit the leukocytosis normally associated with exposure to the toxin. These results demonstrate that the B oligomer, which does not contain the enzymatic activity of the holotoxin, can be used to induce a neutralizing antibody response and suggest that the B oligomer might be considered for use in acellular pertussis vaccines.
