Case of the Week 117

The following images were taken from a Giemsa-stained peripheral blood smear. The different stages of the organism shown represent a single species, and each stage is characteristic for this species. The stages are so characteristic, in fact, that each has an 'unofficial' name (e.g. nick-name) or description.

Question 1 - What organism (genus and species) is shown?
Question 2 - What is the nick-name of each stage?

    Plasmodium malariae. But one has to consider Plasmodum knowlesi.There have been cases of misdiagnosis. PCR can confirm.
