[Taxonometry, ecology and evolutional relation of rickettsia].
Ecology of Rickettsia is main direction of researches of RAMS academician I. V. Tarasevich and her team. Characteristics of alpha 1-Protobacteriae--parasites of eukaryotic cells--given in the work. The accent to Rickettsia characteristics in relation of their evolution relationship with eukaryote mitochondria is made. Main directions of researches in Q-fever, Tsutsugamushi fever, rickettsioses of tick-borne spotted fever (TSF) group, performed in our country under direction of RAMS academician I. V. Tarasevich, are represented. Results of study with the use of tick experimental model, monoclonal antibodies and genetical methods of TSF group Rickettsia, revealed in Siberia and Far East (focal territories of tick-born rickettsioses) and also in territories with the absence of this infection in Russia and Kazakhstan, are given.
