   This is Scientific Americans 60 second Science, I am GretchenKuda Kroen, this will just take a minute.

  When normal populations of healthy bacteria in the gut1 get out of whack2, the result can be the stubborn and recurrent bacterial3 infection known as Clostridium difficile – C-dif.  The main symptom is nearly constant and debilitating4 diarrhea.
  One of the most successful therapies for C-dif is to repopulate the intestines5 with healthy bacteria that keep that nasty C-dif in check. There’s been only one way to do this: import a small sample of a healthy person’s feces. That’s right. A poop-transplant.
  But the “ick” factor of fecal transplants is a hurdle6 for some, as well as a regulatory conundrum7 for the FDA.  Which is why researchers at the University of Guelph in Canada came up with a synthetic8 alternative: a laboratory-made slurry of healthy bacteria they’re calling “rePOOPulate.” The research is published in the journal Microbiome.
  It’s intended to replace human fecal matter in stool transplants, and researchers say it has several advantages. The bacteria are carefully controlled and can betailored to the patient. It reduces the risk of transmitting disease. And, well, it’s just less gross.
  Thanks for the minute for Scientific Americans 60 second science, I am Gretchen Kuda Kroen
