This is a very interesting article. I came to a similiar conclusion after trying to repopulate my gut after cipro. Probiotics were making me sicker so I tried single strains trying to find the right one. Months of this I decided to stop everything and in short order things started to improve. Most strains in the gut are not available in probiotic form and food is the best/only way to repopulate those strains (aside from fme).
