Abstract
Aim. To study the subpopulational structure of blood cells of the experimental animals immunized with cellular walls (CW) of Francisella tularensis different subspecies. Materials and methods. Total 210 certified («Vector», Novosibirsk) outbred mice were immunized with CW preparations of F. tularensis different subspecies in 95 pg protein dose. After 3, 7, 10, 14 and 21 days of observation the phenotypes (CD45, CD3, CD4, CD8, CD19, CD69) of blood cells were detected. Results. Dynamics of leukocyte balance in experimental animals depended on F. tularensis subspecies. All studied preparations promoted development of cellular and humoral immunity that confirmed by the increase of monocytes and B-lymphocyte, and also by the expression of CD69 activation marker. CW of F. tularensis subsp. mediasiatica А-61 promoted higher activation of cellular immunity in experimental animals in comparison with other preparations. Probably, exactly this factor causes its high immunogenic activity (83 % survival rate). Conclusion. On the basis of the results there is a necessity to further detailed research of CW immunogenic properties of F. tularensis subsp. mediasiatica А-61 as a perspective component in design of a tularemia vaccine.
