title: Protection against the lethal effect and arthritogenic capacity of Yersinia enterocolitica serovar O:3 for mice.
abstract: Protection against the intravenous lethal effect of Yersinia enterocolitica serovar O:3 for mice can be achieved by oral immunization with bacteria expressing the O:3 lipopolysaccharide (LPS). Under similar experimental conditions, Ca(2+)-dependent cells are more protective than their Ca(2+)-independent counterparts, live vaccines are more efficacious than killed ones, and parenteral immunization is more efficient than the oral route. Antibodies induced by enzyme-treated LPS from an O:3 strain are able to mediate protection against challenge with one homologous strain, but they do not prevent induction of arthritis.
