Please read my posts on Blastocystis. It does not cause disease is not pathogenic, and I almost killed myself trying to treat that, while I had a different pathogen. Most labs, as the best doctors I saw, confirmed, only detect Blasto initially, and because they mistake something else for Blasto. I also took both triple therapies from Australian CDD, and sadly I would have say, that BOrody and Jackie know thing about parasites.
Only after going to the best doctors, who were able to find what I had, and treating with the proper combinations of drugs, for the proper duration did I get better. Australian drugs will not work for, and read my posts see what happened to me, and how I was midiagnosed with "Blasto" and the kinds of nonsensical drugs I took to eliminate it.
You have something else, and IT sure is not Blasto. That you can take to the bank.
