[The effect of body immunological reactivity on the persistence of rickettsiae].

Correlation between the rate of seeding of organs by rickettsiae and duration of the exciter persistence and condition of immunological reactivity was established using the experimental rickettsial infection as a model. When using the preparation which stimulates the immunity indices, we have revealed that the number of rickettsiae in organs was less and the release from them was faster than under immunodepression.
