exoerythrocytic stage
ex·o·e·ryth·ro·cyt·ic stage
developmental stage of the malaria parasite (Plasmodium) in liver parenchyma cells of the vertebrate host before erythrocytes are invaded. The initial generation produces cryptozoites, the next generation metacryptozoites; reinfection of liver cells from blood cells apparently does not occur. Delayed development of the sporozoite (hypnozoite) of Plasmodium vivax and P. ovale appears to be responsible for malarial relapse that may occur with these disease agents.

The released merozoites invade susceptible erythrocytes and undergo another phase of schizogony, which is relatively faster compared to that at the
exoerythrocytic stage [9].
falciparum.[3] The risk of fatal infection is increased when the patient is asplenic.[6] Since there is no
exoerythrocytic stage associated with transfusion-transmitted malaria, the disease may be treated with therapy that kills the erythrocytic parasites.[3-6]
This scenario implies that not all posttransfusion MPs are blood-induced; the recipients might just have had natural mosquito acquired MPs in the
exoerythrocytic stages during the pretransfusion tests.
