[Humoral and cellular immunity factors in peroral vaccination with an S. typhimurium antigenic complex].
The role of individual immunity factors in protection from S. typhimurium infection was studied on mice immunized orally in a single administration with an antigenic complex obtained by the treatment of bacterial cells with hydroxylamine. The oral administration of this preparation induced the systemic and local transformation of the organism, which was manifested by the accumulation of antibody-producing cells in the immunocompetent organs (spleen, mesenteric lymph nodes) and the increase of the phagocytic activity of macrophages in peritoneal fluid. Cellular immunity factors were found to be important for the development of resistance to salmonellosis caused by S. typhimurium after oral immunization with the antigenic complex.
