Parameters of Cellular Immunity in Acute and Chronic Rickettsia Tsutsugamushi Infections of Inbred Mice
The role of cell-mediated immunity (CMI) has been shown to be a major factor in acquired resistance to the obligate intracellular parasite R. tsutsugamushi. Specifically, it has been shown that immune animals possess spleen cells with the characteristics of thymus-derived lymphocytes (T-Cells) which confer protection against subsequent challenge when transferred to naive mice (9). The interaction of antigens with specifically sensitized T-cells can be demonstrated in vivo by a delayed-typed hypersensitivity (DTH) response (6), or in vitro by a specific antigen induced lymphocyte proliferative (LP) response (7).
