title: [Proteus peritonitis-bacteremia in mice--a model for studying postvaccinal Proteus immunity].
abstract: The dynamics of the formation of postvaccinal immunity after immunization with preparations obtained with the use of hydroxylamine (HA) preparations from Proteus strains of different O serogroups, Salmonella minnesota Re-mutant and the common antimicrobial antigen isolated from Escherichia coli 14 has been studied on mice with Proteus peritonitis-bacteremia used as a model. The study has revealed that intraperitoneal immunization with Proteus HA preparations stimulates the phagocytic activity of peritoneal mononuclear cells in mice and induces an increase in the titers of specific O antibodies. Proteus antigens ensure the formation of anti-Proteus immunity, preventing the death of the animals from peritonitis-bacteremia. The protection of mice from such infection resulting from the injection of the common antigens of gram-negative bacteria is considerably less. These data are indicative of the possibility of using Proteus peritonitis-bacteremia as a model for the study of the protective potency of Proteus vaccines.
