I've been fighting these things that I call "fecal fruit roll-ups" for 3 years, with anthelmintics.
CZ posters have me about 70% convinced that they are flukes, but none of them have answered my challenge. I implore you parasite posters for a link to a medical journal that identifies these easily observed artifacts as flukes. Yes I've read the hundreds of CZ threads that make this ID, but why would medical journals neglect such an easy sign?
Other possibilities that I have considered is that they are rolled up intestinal lining, or just another manifestation of the mysterious Morgellons organism.
