I am convinced that the etiology of many chronic diseases that have been earmarked as "autoimmune diseases" lies in the gut.
The key question then is whether you need special "manipulated" bacteria to cure the situation (as by the above study) or,
alternatively, whether it would not be good enough if you would restore the normal intestinal flora.
The latter is what they do in Amsterdam and in other places around the world for diabetes by gut (flora) transplants,
and also what is being practised for MS with good results that have shown to be sustainable over the years.
Therefore, I do not exclude the possibility that all these stories emerge now (the Mathieu story there is only 1) because all feel that something big is going on,
and that if they do not go public now, in half a year developments will have caught up with them anyhow..
