Human Parasite with Proboscis from Stool Sample - What Is It? I'm flushing out (albendzole and praziquantel) what amounts to a menagerie of parasites from worms to flukes. This one is especially interesting as most examples are damaged (assuming their heads are detached by the time they die and come through as waste). Any photo I post is taken by me with an iphone thru the eyepiece of my compound microscope (100x - 400x typically).
