[Life cycle and nucleic acid distribution in the endogenous development stages of coccidia (Coccidiida, Eimeriidae) of the Vinogradov gerbil].

Studies were undertaken of the life cycles of three intestinal coccidia: Eimeria arabiana, E. bistratum and E. poljanski, parasites of meriones vinogradovi. The number of the asexual generations, the period of appearance of the endogenous stages and the first oocysts, localization were determined. The successive phases of the growth and development of schizonts of different generations, macrogametes and microgametocytes were described. The distribution of DNA and RNA in different endogenous stages of three kinds of coccidia were studied by methods of cytochemistry.
