| Abstract: | As a result of our studies, strain differences in the sensitivity of CBA and BALB/c mice to partially attenuated Francisella tularensis strain have been revealed. Relationship between the increased migration of lymphocytes to the liver and lymphoid organs and the intensive development of cell-mediated immunity reactions has been shown. An important role of local reactions (the skin at the site of the inoculation of F. tularessis + a regional lymph node) in the development of the pathological process and the formation of immunity to tularemia infection has been noted. A high level of resistance to F. tularensis strain used for inoculation in BALB/c mice seems to be greatly due to the fact that in these mice more intensive cell-mediated immunity reactions develop at the early stages of infection, than in CBA mice. |
