Malarial parasites undergo asexual multiplication in the erythrocytes, i.e. erythrocytic schizogony. During the ring stage, this trophozoite, seen here with 2 chromatin dots, will mature into a schizont, which will rupture releasing merozoites. Credit: CDC.

This trophozoite is contained within a normal sized RBC. The compact cytoplasm contains a large quantity of chromatin, often producing a band formation. Towards the end of the trophozoite stage, the parasite replicates its DNA. Credit: CDC.

As the parasite increases in size, the ring morphology disappears, and becomes what is referred to as a mature trophozoite. The trophozoite of P. vivax is ameboid in shape, and the enlarged infected erythrocyte contains numerous Schuffner's dots. Credit: CDC.

An immature trophozoite may mature into an erythrocytic schizont or gametocytes. When the erythrocytic schizont ruptures, merozoites spill into the blood and repeat the cycle of infecting erythrocytes. Credit: CDC.

The immature trophozoite (ring stage) of the P. malariae parasite has a sturdy cytoplasm and usually one large chromatin dot. These parasites may mature into an erythrocytic schizont or gametocytes. Credit: CDC.

This growing trophozoite is contained within a normal sized RBC. The parasite is developing larger chromatin, and is forming a more compact cytoplasm. Credit: CDC.
