Case of the Week 677

This week's case came through my lab awhile back and was beautifully captured in the following photographs by Emily Fernholz. The specimen is a Giemsa-stained thin blood film from a patient with travel to Botswana. What parasite is seen here?

Plasmodium malariae

Marco Ligozzi said...

In order: a basket form of P malariae contains a large eccentrically vacuole that is pushing the chromatin to one side to form the handle of the basket. A rosette forming Schizont 11 merozoites with large nuclei, clustered around mass of coarse, dark-brown pigment; Finally a band occupies about one-third of the lengh of an erytrocyte

Everything that need to be said has been spoken. The infected red blood cells are slightly smaller than the normal cells, denoting a predilection for older red blood cells, a characteristic typical of P. malariae. Some how I counted twelve merozoites in the first schizont. Beautiful case indeed.

Plasmodium malariae, definitively: Small parasitized red blood cells, including band forms and schizonts with eight to twelve merozoites.
