[Morphofunctional evaluation of the immunogenicity of a live brucellosis vaccine].

The possibility of evaluating the immunogenic potency of brucellosis vaccine BA-19 by immunological methods has been shown. Morphometry and the quantitative evaluation of globulin-producing cells in lymphoid organs by direct and indirect immunofluorescent techniques serve as informative evaluation tests. The marker method with the evaluation of lymphocyte classes by acid and alkaline phosphatases and the electrophoretic motility characteristics of T- and B-lymphocytes, used in combination with the above-mentioned methods, present information on immunogenesis. The immunoperoxidase method and the values of the opsonophagocytic index characterize the state of phagocytosis and the persistence of the antigen.
