The photos look like candida strings--the invasive, fungal form of candida.
If you're getting this kind of results, it looks like ACV is working pretty well for you. I also had fairly good results with vinegar, but better results with daily Miracle-Mineral-Supplement enemas.
In my reading, I just discovered that candida can modulate the immune system, as do helminthes. So it's important to get rid of it.
