Tachyzoites of Toxoplasma gondii. Crescent shaped, pointed anteriorly and rounded posteriorly. The nucleus is spherical, near the rounded end.

Tissue cyst of Toxoplasma gondii. Rounded, with a tough cyst wall. The cyst contains hundreds of bradyzoites.

Ring of Plasmodium Vivax. Delicate plae blue ring enclosing a vacuole with red chromatin dot representing the nucleus. The ring is 1/3 of the diameter of the infected RBC. The infected RBC is of normal size.
Trophozoite of Plasmodium Vivax. Amoeboid in shape with vacuole and a single chromatin dot. Size is about 2/3 of the infected RBC. Infected RBC is enlarged, irregular in shape containing Schuffner's dots in its cytoplasm which appear as fine red granules.
