One of the neat things about being a researcher is that I go to all kinds of interesting seminars (not all seminars are interesting, but every once in a while there is truly a gem). The other day, I went to a seminar on Clostridium difficile, which is a nasty bug that infects your colon, and I found out some things I didn't want to know... as sometimes happens when a bunch of curious scientists get into a long discussion about poop.
Clostridium difficile rears its ugly head when you've taken a bunch of antibiotics and killed all the good bacteria that are normally in your colon. When Clostridium difficile takes over, you start havinng all kinds of problems. It's tough to get rid of, and a nasty bug to have, so people have started getting creative to treat it. To date, one of the most effective treatments (still considered an alternative treatment but consistently effective nonetheless) is to get an enema with... someone else's poop.
I'll give you a minute to think about that.
Then you can read about it here if you want to think about it some more.
See, a normal person's poop is full of really good stuff (bacteria) for your colon, and the theory is that if you put all that good stuff back in your colon the Clostridium difficile will get displaced by it and normalcy will resume.
But... you'd have to be pretty desperate to get a poop enema!
