Abstract

Intraperitoneal immunization with a bacterial protein antigen conjugated to cholera toxin B subunit (CTB) was generally less effective than intragastric or intranasal immunization in generating mucosal IgA antibodies, and in priming the mucosal immune system to respond to intragastric or intranasal boosting. Previous intragastric or intranasal immunization which generated high levels of mucosal and circulating antibodies to CTB did not suppress mucosal IgA responses induced by intragastric or intranasal immunization with bacterial antigen conjugated to or mixed with CTB, but serum antibody responses were inhibited depending on the route of immunization and whether CTB was conjugated to or mixed with the antigen.
