Schüffner’s dots can be demonstrated in Giemsa stain, which is preferred to Wright or Wright-Giemsa stains. In P. ovale infections, red blood cells (rbcs) can be normal or slightly enlarged (up to 1 1/4×) in size, may be round to oval, and are sometimes fimbriated. Under optimal conditions, Schüffner's dots may be seen in Giemsa stained slides. 1.
Plasmodium ovale - Wikipedia
Plasmodium ovale is a species of parasitic protozoon that causes tertian malaria in humans. It is one of several species of Plasmodium parasites that infect humans, including Plasmodium falciparum and Plasmodium vivax which are responsible for most cases of malaria in the world.
CDC - DPDx - Malaria
Plasmodium falciparum is the predominant species in the world. P. vivax and P. ovale are traditionally thought to occupy complementary niches, with P. ovale predominating in Sub-Saharan Africa and P. vivax in the other areas; but their geographical ranges do overlap.
Certain morphologic key characteristics of the infected erythrocytes and parasites can be used to orient the diagnosis towards one of the four Plasmodium species that infect humans,as shown above.These characteristics are by no means absolute, however.The final diagnosis should be based on the combined findings for the various characteristics: w...

2023年8月14日 · P. ovale spends about 50 hours in an erythrocytic cycle. By the end of the 50 hours, the parasite has consumed nearly all of the hemoglobin and grown to occupy most of the red blood cells. At this stage, it is called a schizont. A single P. ovale sporozoite may produce about 15,000 daughter merozoites per infected hepatocyte.

Plasmodium ovale schizonts have 6 to 14 merozoites with large nuclei, clustered around mass of dark-brown pigment. Red blood cells are normal to slightly enlarged (1 1/4×), may be round to oval, and are sometimes fimbriated. Schüffner's dots are visible under optimal conditions.
