Plasmodium cynomolgi and other related simian species have identical biology and can serve as informative models of P. Life cycle of Plasmodium 1 Plasmodium -infected Anopheles mosquito bites a human and transmits sporozoites into the bloodstream. These merozoites are subsequently released into the blood where they initiate the erythrocytic stage.

It has a dormant stage in the human liver which makes it difficult to eradicate. Stages in the Life Cycle of Plasmodium. 1 Gametocytes Stage 1 The male gametocytes called microgametocytes and female gametocytes called macrogametocytes are transmitted through an anopheles mosquito during a blood meal.
