1. Ring forms: Plasmodium falciparum appears as ring-shaped structures within red blood cells in a blood smear. These rings are small and often have a single chromatin dot.
2. Multiple infection: Unlike other species of Plasmodium, P. falciparum often infects multiple red blood cells simultaneously. This characteristic is known as "multiple infection" and can be observed as clusters of infected cells in the blood smear.
3. Maurer's clefts: P. falciparum-infected red blood cells may exhibit Maurer's clefts, which are small, dark-staining structures located at the periphery of the infected cell. These clefts are involved in the export of parasite proteins to the host cell membrane.
4. Schüffner's dots: Another characteristic feature of P. falciparum in blood smears is the presence of Schüffner's dots. These dots are small, pinkish-red granules that appear within the cytoplasm of infected red blood cells. They are more prominent in mature stages of the parasite.
5. Crescent-shaped gametocytes: In addition to asexual forms, P. falciparum also produces sexual forms called gametocytes. These gametocytes are crescent-shaped and can be observed in the blood smear. They are responsible for the transmission of the parasite to mosquitoes, which then spread the infection to other individuals.
