I happened to read this thread and was reminded of something I heard last fall. It may or may not be related but might be worth a look-see, rather a listen. The context is also centered on gut, flora, parasites, but related to Autism.
The podcasts are of Kerri Riveras from OneRadioNetwork. It might be worth a listen to the first few minutes to see if you might be able to glean something of value.
Also, I in no way endorse the use of MMS. That subject seems to draw a lot of opinion fer and agin. I found the information by itself to be fascinating. Maybe there is something useful in this?? FWIW, a $0.02, etc etc....
