Description:This photomicrograph revealed the presence of a trichrome-stained, Dientamoeba fragilis parasitic trophozoites in this specimen.
Dientamoeba fragilis is a flagellate that must be morphologically differentiated from the small nonpathogenic amoebas. D. fragilis has no cyst stage, and its trophozoites measure 5 to 15┬Ám. The flagella are not usually evident and the pseudopodia are angular to broad-lobed and transparent. While most trophozoites are typically binucleate, some have only one nucleus, as was the case here.
