[Cytochemical study of various stages of life cycle of Toxoplasma gondii. 10. Phosphatases in the parasites during developmental stages in cat's intestines].
Several methods of acid and alkaline phosphatese and ATPase detection using both natural and artificial substrates were applied to the intestinal stages of Toxoplasma gondii with negative results to reveal enzymatic activity in all the stages except the microgametocyte. Possible explanation of this unexpected phenomenon is discussed taking into account host-parasite relationships with intestinal stages of Toxoplasma and with coccidia in general.
