I guess this was the next step, after blood banks, and human milk banks, the next big advance is a poop bank.

Although we don’t know if autologous stool transplants will be as successful as donor stool to treat C difficile, it sounds like a good idea, and a Toronto Hospital is accepting poop from its patients which can then be thawed and given back to them if they develop the condition. http://news.nationalpost.com/2013/11/04/na1105-poopbank/
