In some cases more than one parasite (most often though not always early or late trophozoites) infect a single erythrocyte. This is a surprisingly frequent finding, and it has been suggested some red cells are ore attractive to parasites, or that already infected cells are more susceptible.
The most frequent form - two early trophozoites of P.falciparum in a single erythrocyte
Species significance This is most often considered a feature indicating P.falciparum infection and is sufficiently frequent in that species to support the diagnosis of P.falciparum malaria. However, it should not considered as a fully specific feature, and may occur in any malaria species - and particularly in P.knowlesi (this is also a frequent finding for babesia parasites).
