I do not see any forms that are recognizable as parasites. The stools have come out the shape of your intestine and the clear area (bubbles) are gas pockets. Two images show blood, unless you have been eating beets, and there is no bile to give a dark brown color to the stools. I assume you have been treated for the Blastocystis (parasites) so you might just go ahead with the Liver Flush and then do the preparations before the next flush. Choose one of the programs featured - Clark or Schultze's might work best. Also Look at Dr. Sutter's Liver Flush. It is going to take many LFs to clear out your bile system and they may be difficult to do at first.
Make sure you have had complete testing for Celiac Disease (Celiac Sprue) as there is no cure for that autoimmune problem except going on a strict gluten free diet. See the information pages at http://www.Celiac.com.
Some people who have been told that they have IBS actually have Celiac Disease. The blood tests are more likely to be positive for CD only if the person is eating sufficient gluten containing foods however these blood tests are false negatives in about 20 to 30% of people with this problem.
