My Suggestion
If you are serious about trying to identify anything in feces. you will have to do a proper job.
Separate objects. worms or whatever else from the feces. wash it with clean water. Place it on a clean paper plate or something similar. take a high resolution photo under a good light. best use daylight to get correct colors on the photo.
Than publish the photo.
It does not help much to show us photos of feces with something inside. That something can be actually just about anything.
