 Amastigote form of Leshmania. They are small rounded or oval organism and present either inside or outside of the macrophage cell. 

Promastigotes of Leshmania. Spindle shaped. The flagella is long originating from the basal granule.

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.

Schizont of Plasmodium Vivax. contains 12-24 chromatin dots. Infected RBC is enlarged with Schuffner's dot

Gametocyte of Plasmodium Vivax. Rounded enlarged mass of compact cytoplasm with a single nucleus which is compact and peripheral. It is large filling the enlarged RBC. Infected RBC is enlarged, irregular filled with Schuffner's dots.

 Ring of Plasmodium falciparum. Delicate ring of blue cytoplasm enclosing a vacuole with a red chromatin dot. The ring is about 1/6 of the diameter of the infected RBC. Accole phenomena or marginal form may present. The infected RBC is of normal size.

Gametocyte of Plasmodium falciparum. Crescent or banana shaped. The infected RBC is of normal size and stretched.

Plasmodium ovale. Rouned not filling the infected RBC. Nucleus is central and diffuse. Infected RBC is enlarged, oval in shape, crenated and containing Schuffner's dots which appear as fine red granules.
