P.falciparum gallery of late trophozoites


Summary The schizonts of P.falciparum sequester in the small vessels and rarely circulate in blood; when found they usually signify a very severe infection. If this is not the case then it is appropriate to ask if there is a different species causing the infection. Generally these are loosely formed with variable numbers of merozoites and a single clump of pigment, they are not "neat" like the parasites of P.malariae.

  • Late rings Two cells both with typical dots: multiply infected and double dot forms
