title: [Isotypic characteristics of serum and secretory O antibodies and local immunological memory in the parenteral immunization of guinea pigs with a ribosomal Shigella vaccine].
abstract: Guinea pigs were immunized subcutaneously with ribosomal vaccine prepared from S. sonnei and their systemic and local humoral response was studied by means of ELISA techniques with the use of monospecific antisera to guinea pig IgA and IgG. Injection of the ribosomal vaccine leads to a significant rise in the levels of IgA O-antibodies in tears, IgG and IgA O-antibodies in the serum. The presence of IgA O-antibodies in tears was seemingly the result of their local synthesis rather than the seepage of serum IgA. The stimulation of the local and systemic anti-O response was more pronounced after parenteral immunization with the ribosomal vaccine than after immunization with the corresponding dose of lipopolysaccharide (LPS). Parenteral immunization with the ribosomal vaccine induced the development of both systemic and local memory. The priming effect produced by relatively small doses of this vaccine (40 micrograms), administered parenterally, was similar to the effect of prolonged and intensive stimulation ensured by 10-day feeding with LPS (the total dose being 5,000 micrograms).
