- It comprises a single cycle and lasts for six days.
- The mature pre-erythrocytic schizont measures 60 micro meter in length and 30 micro meter in breadth.
- It contains numerous small merozoites about forty thousands in number.
Merozoites enter in to RBC to start erythrocytic schizogony. These merozoites are liberated on the 7th day of infection and enter in to RBC to start erythrocytic schizogony. It is now known that they do not re-enter into the liver cells and pre-erythrocytic schizogony disappear completely without giving rise to late tissue phase.
Plasmodium falciparum does not show special affinity for any particular type of RBC but invades both the reticulocytes and erythrocytes (i.e. both young and mature RBC).
Schizogony occurs inside the capillaries of the internal organs (spleen, liver and Bone marrow) hence only the ring form (but not the growing trophozoites and schizonts) are found in the peripheral blood.
The cycle of schizogony is completed in about 36 to 48 hours.
Multiple infection of the RBC i.e. more than one Plasmodium falciparum parasite invades a single RBC (Generally 2-6 parasite).
Exo-erythrocytic schizogony is completely absent in Plasmodium falciparum. So in falciparum malaria relapses does not occur.
