Giemsa stain is called a differential stain because it produces different colors depending on what it bonds to, such as cytoplasm or DNA. The formula for Giemsa stain has been adjusted over time to improve the stability of the dyes and the colors that result. Current standard mixtures include methylene blue, eosin, and sometimes azure B.


The blood films stained with Giemsa or Romanowsky stain show ringlike intraerythrocytic parasites. Morphology is variable, and ring, rod, and ameboid forms of Babesia parasites may be seen (Fig. 158.16). 276 Occasionally, multiple intraerythrocytic forms can be seen, linked to form a tetrad or, colloquially, a “Maltese cross.” However, at low parasitemia, Babesia parasites may easily be ...


Giemsa stain is a staining reagent that was developed in the early 20th century by Gustav Giemsa to aid in cellular microscopy. Different cells and parts of cells stain slightly different colors, allowing appropriate diagnoses to be made.
