2 CD8 cytotoxic T. Plasmodium sporozoites injected by an infected mosquito migrate to the liver and initiate the hepatic stage of the parasite life cycle by invading hepatocytes within which they multiply and differentiate into schizonts containing thousands of hepatic merozoites. The life cycle of plasmodium in man is can be studied under the following heads.

From there the sporozoites infect the liver cells and disappear from the bloodstream within approximately 30 minutes. Sporozoites infect liver cells and mature into schizonts which rupture and release merozoites. Plasmodium parasites have a complex life cycle that includes three stages namely Gametocytes Sporozoites and Merozoites.
