title: Immunization with Pseudomonas aeruginosa high-molecular-weight polysaccharides prevents death from Pseudomonas burn infections in mice.
abstract: High-molecular-weight polysaccharides from the extracellular slime of Pseudomonas aeruginosa were evaluated as immunogens in Pseudomonas burn infections in mice. Immunization with immunotype 1 or 2 polysaccharides induced a strong immunotype-specific and weak cross-reactive antibody response but protected mice against burn infections caused by either immunotype. Passive protection was provided by rabbit antiserum to immunotype 1 polysaccharide against burn infection by the homologous organism. Pseudomonas high-molecular-weight polysaccharides are potentially effective vaccines in burn infections.
