Medical Definition of Plasmodium ovale
1. A species that is the agent of the least common form of human malaria; resembles Plasmodium vivax in its earlier stages, but often modifies the cell membrane, causing it to form a fimbriated outline, and often assume an oval shape; Schuffner's dots are abundant and appear early, host cells are normal or only slightly enlarged, and only about 8 to 10 grapelike merozoites are produced; fever is tertian (every 48 hours), and relapses are infrequent.
