title: [Study of the immunological activity of blood in various rickettsial and viral infections].
abstract: The content of various types of antibodies were studied in the blood serum of laboratory animals in experimental tick-borne rickettsiosis of Northern Asia. This was done by a simultaneous staging of indirect hemagglutination, indirect hemolysis, compliment fixation under cold conditions, and agglutination with Proteus antigen OX19 tests. Immune horse sera to the influenza virus were also studied with the aid of several serological tests. The data obtained pointed to the significant differences in the properties of individual types of antibodies. Immunological activity of the sera under study depended on the correlation in them of various types of antibodies at various periods of the infectious process in combination with the influence upon the immunogenesis of the individual and species immunological reactivity.
