We studied the expression of activation markers CD25 and CD69 by blood lymphocytes in white mice vaccinated with Brucella abortus 19 BA in antigen-specific tests in vitro. During incubation of blood lymphocytes with brucellosis polysaccharide-protein antigen, a statistically significant increase in the expression of CD25 by B cells and CD69 by T cells was observed; brucellin increased the expression of CD25 by B and T cells. Comparative analysis of the action of antigen preparations B. abortus showed that only brucellin has antigen-specific activity against CD19+CD25+ cells. The used method can be considered as a promising test for evaluation of the effectiveness of brucellosis immunoprophylaxis, which substantiates the need for further research.
