Female Anopheles mosquito is the primary host of Plasmodium in which it completes its sexual life cycle. 1 Gametocytes Stage 1 The male gametocytes called microgametocytes and female gametocytes called macrogametocytes are transmitted through an anopheles mosquito during a blood meal. Ovale show a slightly different life cycle within the mammalian host as some sporozoites once in the liver do not develop immediately into schizonts but remain at an uninucleate stage in a quiescent form named hypnozoite before resuming hepatic development on the impulse of still unknown factors causing relapses weeks months or even years after.

Now we are center stage in the red blood cell. We are going to study it in detail. It has a very complex life cycle.

It has a dormant stage in the human liver which makes it difficult to eradicate. Man and female Anopheles mosquito. Vivax is sometimes referred to as tertian fever Anemia is the most common presenting symptom.
