Parasitology Challenge: Identifying an Object in Stool

A diagnostic challenge in stool microscopy: differentiate a suspicious object in a native glycerin preparation at 400x magnification.

Anonymous question from a subscriber. Please tell me, please, is this E.coli or something else? By the number of nuclei and shape, it doesn’t seem to be a cyst. Stool, 400x magnification, glycerin.
