Erythrocytic Cycle
This stage occurs in the red cells of the blood:
- Merozoites invade erythrocytes
- Trophozoites grow in red cells to form more schizonts (asexual reproduction) or gametocytes (sexual reproduction)
- Schizonts rupture and release more merozoites (asexual) or mosquitoes take gametocytes in next blood meal
This phase of infection repeats itself, unlike the exo-erythrocytic cycle.
Clinical symptoms don't manifest until haemolysis begins to occur.

Merozoite : A growing stage capable of initiating new sexual or asexual reproductive cycles that arises from asexual fission ("mero" = part).
Trophozoite : An erythrocytic stage where the parasite grows through absorbing host nutrients ("tropho" = obtaining food).
