Apicomplexan life cycle - Wikipedia
A trophozoite (G. trophē, nourishment + zōon, animal) is the activated, intracellular feeding stage in the apicomplexan life cycle. After gorging itself on its host, the trophozoite undergoes schizogony and develops into a schizont, later releasing merozoites.

The ring stage trophozoites mature into schizonts, which rupture releasing merozoites . Some parasites differentiate into sexual erythrocytic stages (gametocytes) . Blood stage parasites are responsible for the clinical manifestations of the disease.
Schüffner’s dots can be demonstrated in Giemsa stain, which is preferred to Wright or Wright-Giemsa stains. In P. falciparum infections, red blood cells (rbcs) are normal in size. Typically only rings and gametocytes are seen unless the blood sat before the smears were prepared. 1.
Schizont | biology | Britannica
…targets Plasmodium organisms in the schizont stage of development. Schizonts, which mature from sporozoites—the form of parasite transmitted to humans in the saliva of Anopheles mosquitoes—contain insoluble iron called hemozoin. Hemozoin is formed within schizonts as they feed on hemoglobin in the cytoplasm of human red blood
Plasmodium schizogony, a chronology of the parasite’s cell cycle …
Mar 2, 2023 · Extensive Plasmodium proliferation inside erythrocytes causes all malaria-related pathology and generates high numbers of progeny by an unconventional cell cycle mode, termed schizogony.
Etiopathogenesis and Pathophysiology of Malaria - PMC
The sporozoites rapidly grow in size absorbing nourishment to form a large round schizont. The schizont divides by schizogony, a type of asexual reproduction, in which multiple fissions result in the formation of a number of small, spindle-shaped uninucleate cells called merozoites (Rogier and Hommel 2011). After schizonts rupture, merozoites ...
Schizont - an overview | ScienceDirect Topics
Schizont: the stage of P. falciparum intraerythrocytic asexual development from the onset of parasite nuclear division to the production of the progeny of individual mature merozoites (Figure 1) ready to disrupt the surrounding parasitophorous vacuole and erythrocyte membrane in the process of schizogony.

Mar 2, 2023 · Classically, the distinction between the trophozoite stage and the schizont stage has been made morphologically, and a schizont is often referred to as a multinucleated cell, i.e., a cell with more than two nuclei.
Malaria - Medical Microbiology - NCBI Bookshelf
Each merozoite can infect a red blood cell. Within the red cell, the merozoite develops to form either an erythrocytic-stage (blood-stage) schizont (by the process of erythrocytic schizogony) or a spherical or banana-shaped, uninucleate gametocyte.
Malaria Parasite Schizont Egress Antigen-1 Plays an Essential Role …
Mar 9, 2021 · To assess the effects of the SEA1-null defect on merozoite egress, we monitored the fate of highly synchronized schizont populations using established approaches to measure schizont rupture and RBC invasion by the released merozoites.
