I have no idea what you are talking about. I am talking about Human microbiota. You seem to have drifted into some other subject or something. All I ever states was that Probiotics do not establish in the GI tract and that they do not cure. These are facts. If you do not comprehend this then that is your problem.
If you do not know that the fact that the beneficial gut microbiota are also known as flora and thus we are talking about the same thing then you obviously never did your homework. No wonder why you do not understand the facts that not only do they establish in the intestines, but they also perform a number of beneficial effects on the body including helping with healing in large part by reducing pathogens and inflammation. Seems that all of science and everyone who has looked in to it know this fact. But I guess on your planet the flora serve no beneficial purpose. But here on Earth these flora are essential to the health of us humans!!!
