What are double infected cells?
In some cases more than one parasite (most often early or late trophozoites) can be seen within a single erythrocyte.
Note how the chromatin dot of the ring form is divided into two purple masses
Species significance
Most often considered a feature indicating P.falciparum infection, and is certainly frequent in that species where it can be used to support the diagnosis. However, the form should not considered as specific, and may occur in any species (and is also a frequent finding for babesia parasites).
