title: [An ELISA study of the intestinal and serum anti-LPS antibody response in BALB/c mice fed with various mutants of "Salmonella typhi-murium" (author's transl)].
abstract: The specific anti-LPS serum antibody response in BALB/c mice, before and after an oral booster with different non-pathogenic strains of Salmonella typhi-murium, was measured by an ELISA technique. Serum response to LPS was found to depend on the length of the LPS polysaccharide moiety in "rough" mutants. The M206 "smooth" mutant induced a less marked anti-LPS response. The immunogenicity of the polysaccharidic "core" appears to be modified by the O antigen. The specific antibody response in the gut only becomes marked following after booster of Ra, Rc and M206 mutants.
