Case of the Week 597

This week ' s case is very timely, as we are seeing a lot of these objects in some of our stool specimens submitted for routine ova and parasite exam. They measure approximately 8-10 micrometers in dimension (shown at 500x and 1000x). Identification? What additional stain or study would you like to do?
