LIFE CYCLE OF MALARIAL PARASITE

1. Infected mosquito injects sporozoites.

2. Sporozoites migrate to the liver where they formed merozoites.

3. Merozoites are released and invade the RBC

4. In the red blood cells, merozoites become trophozoites.

5. In the red blood cells, the trophozoite multiple, producing new merozoites. these are released when the RBC ruptures, and can infect other RBC.

6. Some merozoites become gametocytes.

7. The female mosquito picks up gametocytes from an infected human. the sexual cycle occurs in the mosquito, where sporozoites are formed.

1. Unembryonated eggs passed in feces.

2. Eggs embryonate in water.

3. Coracidia hatch from eggs and are ingested by crustaceans.

4. Procercoid larvae in body cavity of crustaceans
