On IBD forums I read of a man with ulcerative colitis who cured himself of his symptoms by taking his 1 year old baby's poop, mixing it into an enema bottle and implanting himself with this. He reported after being free of symptoms where no chemical medicine was working anymore for him.
I also read that two doctors in Canada (and doctors in Australia) perform Fecal Transplant - get shit from a healthy donor, screen for parasites, pathogenic bacterias, etc. then make it into a fecal smoothie which they then inject through a tube in the nose all the way to the small intestines.
It is a treatment covered by the government in Canada for clostridia difficile - hospitalied patients with this deadly diarrhea. And apparently it works 100%.
It is a wonder that this cannot be done on a more widescale to restore the good flora in our intestines.
I even called one of these docs in Canada (his name is Silverstein I think) and tried to get in to do it. But they only do it for these clostridia difficile cases. And IBD. I think what he does is show people how to do it, but am not sure 'cause the secretary was very uncooperative.
In any case, is this what you mean by human probiotics transfer?
