This week's case was generously donated by Dr. Richard Bradbury. The following were seen in a stool specimen from a middle-aged man with diarrhea. Preparations are a concentrated wet prep and trichrome stained permanent mount. Object measure 10-15 micrometers long. What is your identification?

Looks like a trophozoite stage of an amoeba. My guess is Entamoeba histolytica
The shape and size are compatible with cyst and trophozoites of Chilomastix mesnili. This organism is usually considered a commensal, as such I do not know its role in the diarrhea. Could it be something else?
