“You’re kidding, right?” No, I’m not. Turns out you can cure people from some pretty serious intestinal infections using feces (yes, “ewww” factor and all) from a healthy “donor”. The key is not a single bacterium, but more a competitive culture of dozens of different bacteria, keeping each other in check.
Expect the concept to be expanded significantly beyond donated feces to a standardized competitive culture (already in use in livestock), and then possibly to skin infection treatment, anti-acne creams, and maybe even mouthwash and shampoo!
Still in its infancy though, and there are quite a few sham probiotics out there that are either useless or harmful. Wait for the scientific testing to catch up with it.
