Your fecal coliforms will kill other people, simply because they're yours, not theirs. They'll kill you if they don't stay in the gut (mine tried, along with a carbapenem-resistant strain of streptococcus introduced via a central line).

"A regime of concentrated AO+ caused a hundredfold decrease of Propionibacterium acnes"

The way I see it, both methods (using detergents or probiotics) are achieving the same effect: a decrease in harmful bacteria. The only difference is when probiotics are used, there is a lessened chance of a harmful microbe overgrowth.

I can't reply directly to "rosser" due to max comment depth, but fecal transplants don't generally involve introducing gut bacteria to anywhere other than the gut.

Then why are physicians performing fecal transplants?

[Fomite]

Fecal transplants are typically done with stool either very similar to your own in terms of the microbial makeup (preferably a family member that lives with you) or with synthetic, cultured stool that has been made free of pathogens.

It's still not a fun procedure, and the side effects are unpleasant. They're just less unpleasant than recurrent C. difficile.
