Aim – heterogeneous populations of blood leukocytes and abdomi- nal cavity of mice immunized with a capsular antigen of a plague microbe. Male mice of the BALB / c line were used in the work. The reaction of the cells of the immunophagocytic system was assessed by flow cytometry, in terms of the intensity of direct and lateral light scattering, correlating with changes in the cell volume and intracellular granularity.
