Even better is that research like that of the Human Microbiome Project http://www.hmpdacc.org/ combined with DNA technology, will allow researchers to develop certain bacterial/fungal markers associated with these diseases, and therefore, develop a new class of drugs using probiotics tailored to the condition of the individual. It makes sense that we will have to use probiotics to reverse all of the damage caused to the microbiota by modern medicines especially that of Antibiotics .
