Ultrastructural study on the erythrocytic schizogony of Plasmodium vivax.
Erythrocytic schizogony is initiated by repeated division of the nucleus in rapid sequence. Another important feature of the developing schizont is the reappearance of segments of thick inner membrane and formation of lobes around these segments. These bulbous protuberances signal the start of budding process which ends in complete segmentation of the cell. The cytoplasmic organelles which de-differentiate at the beginning of trophozoite stage are formed again. Asynchrony during merozoite formation is observed in some schizonts where fully mature merozoites are seen lying in the parasitophorous vacuole while the mother cell is still in the process of giving rise to new merozoites.
