ENHANCEMENT OF ANTI-SHIGELLA LIPOPOLYSACCHARIDE (LPS) RESPONSE BY ADDITION OF THE CHOLERA-TOXIN B SUBUNIT TO ORAL AND INTRANASAL PROTEOSOME SHIGELLA-FLEXNERI-2A LPS VACCINES
Addition of the cholera toxin B subunit to oral and intranasal proteosome-Shigella flexneri 2a lipopolysaccharide vaccines improved their immunogenicities. Enhancement of anti-O-Shigella immunoglobulin A levels was most evident in lung lavages following oral immunization and in lung and intestinal fluids when suboptimal doses were used with either immunization route.
