I don't know. While the skins that I find don't look that scaly or have as much of a pattern when comparing them to yours. I really don't know what else it could be. I really only have a familiarity with the fasciola and Tapeworm parasites. The thing is I don't know of any worm that would have skin that would unravel like that and look like that. The tapeworm, I'm assuming both beep and pork tapeworms, come out in segments and I can't make out any particular pattern to them. They aren't scaly like that.
I would guess the fasciola species first and go from there. Try to get some triclabendazole or fasinex. I have some fasinex but I'm away from home right now and just don't have access to it. I think I will be back in a couple of days.
I just don't know what else it could be besides a type of fluke. Another option to try would be to follow the ICU protocol with praziquantel and see how that goes. That's what I would try first. Unless there's another explanation. I just don't know what that would be..
