A panel ofSalmonella typhimurium14028s mutants, which were previously shown to be highly attenuated in the BALB/c mouse model of infection, were analyzed for their potential as liveSalmonellaoral-vaccine candidates. A prototypicalaroAmutant was chosen as a basis of comparison. From the panel of mutants initially chosen for this study, three mutants with comparable levels of attenuation elicited higherSalmonella-specific serum immunoglobulin G (IgG) and/or mucosal secretory-IgA antibody titers than thearoAvaccine strain. The three mutants, CL288, CL401, and CL554, also elicited a better protective immune response than thearoAcontrol strain, after a single oral dose of 1 × 109to 2 × 109bacteria.
