Abstract:
After the merozoite entered the erythrocyte,the membrane debris in the parasitophorous vacuoles of early ring form was passed out through a narrow external aperture in erythro-cyte to the exterior.The trophozoite was oval or irregular in shape.Ingestion of host cell cytoplasm occurred cystostomally.The asexual parasite possessed acristate mitochondria and was surrounded by a single-membraned pellicle.The gametocyte possessed cristate mitochondria and was surrounded by two unit membranes.The cytoplasm of mature macrogametocytes contained many ribosomes,mitochondria and osmiophilic bodies and a small nucleus while microgametocytes contained fewer ribosomes,osmiophilic bodies and mitochondria and a large nucleus.Three characteristic morphological alterations were observed within the host cells,that is,small vesicles,cytoplasmic cleft and caveola-vesicle complex.The clefts within the cytoplasm of the host erythrocytes were present in all human malarial parasites.The small vesicles distributed all over the cytoplasm were surrounded by a unit membrane.The caveola-vesicle complex consisted of caveolae was surrounded by small vesicles and probably corresponds to a Schuffner's dot.(Figs.1-13)
