Abstract
The fine structure of merozoites of a rat coccidian, E. miyairii. has been studied. The merozoites are banana-shaped and are enclosed by a plasma membrane and an inner, thicker membrane composed of 2 layers. Twenty-six evenly spaced microtubules are oriented longitudinally just beneath the inner membrane. A polar ring is present at the anterior and possibly also at the posterior end. The nucleus is located posteriorly and shows an anterior depression facing the Golgi complex. The merozoites contain 3 different kinds of granules. A so-called paired organelle passes through a conoid inside the anterior polar ring to about the middle of the cell. An imagination of the plasma membrane at the middle of the merozoite is considered to be a cytostome. The residual body of the schizogony is described; this has no inner membrane and no microtubules are present The ultrastructure of the organelles of various representatives of Telosporea is compared with those in species of Toxoplasmea.
