Original Investigations


The fine structure of the different stages ofH. aegypti inside its hostSpalerosophis diadema was studied. The ultrastructure of the merozoites is similar to that of the differentiated parasites (=gamonts) in the erythrocytes; all showed the general architecture of the motile stages of the Coccidia. The merozoite (9×2 μm) was covered by a pellicle of two layers; the inner layer was interrupted at the polar ring and the micropore. The parasite had a conoid, rhoptries, and a large number of micronemes (127–135). Both rhoptries and micronemes were usually found on both sides of the nucleus. The merozoite (and its adult intraerythrocytic stage: the gamont=13–16×3 μm) was characterized by 73–75 subpellicular microtubules and all the typical cytoplasmic organelles as mitochondria, Golgi apparatus, endoplasmatic reticulum (rough and smooth), some amylopectin granules and a few lipid droplets. Schizogony ofH. aegypti took place exclusively in the endothelial cells of the lung capillaries producing about 15–40 merozoites by ectomerogony.
