Summary
The fine structure of the microgamonts and microgametes of coccidia and related groups was investigated and is herein described and diagrammatically depicted. Particular attention is given to the developmental processes during the differentiation of the microgametes. The species included in the study are: Eimeria perforans, E. maxima, E. tenella, E. auburnensis, E. falciformis, and Toxoplasma gondii. A comparative analysis of the developmental processes as well as the fine structure of the microgametes of these species and those of other Sporozoa is presented.
