Reactogenic property and immunological efficacy of the paratyphoid preparation containing a complex of O-, K- and H-antigens obtained by single-stage antigens extraction were studied in a limited group of volunteers (22 persons). The antigen gave no untoward reactions and proved to be safe when given orally in doses of 25 to 150 mg. Paratyphoid B antigen was characterized by a marked immunization activity and stimulated formation of specific paratyphoid O-, K- and H-agglutinins and antibodies of the IgA,- IgG,- and IgM-classes.
