Three types of schizogony (asexual reproduction by multiple fission) in the life cycle of Plasmodium:
- Pre-erythrocytic schizogony: It occurs in liver. When female Anopheles mosquito bites a healthy human being, it releases Plasmodium, which lives in its body as sporozoite (infectious form). The parasites multiply (asexual reproduction) in the liver cells and finally burst the liver cells. Sporozoites are released in blood.
- Erythrocytic schizogony: Parasites enter RBCs and further multiply (asexual reproduction) here and finally burst RBCs also. Bursting of RBCs is accompanied by release of a toxic substance called haemozoin (associated with fever and chills).
- Exo-erythrocytic schizogony: Some cryptomerozoites released by liver invade the fresh liver cells instead of RBCs and start exo-erythrocytic schizogony.
