 　　When normal population of healthy bacteria in the gut get out of whack, the result can be the stubborn and recurrent bacterial infection known as Clostridium Difficile, C Dif. The mean symptom is nearly constant and debilitating diarrhea. One of the most successful therapies for C Dif is repopulate intestines with healthy bacteria that keep that nasty C Dif in check. There is been only one way to do this. Import a small sample of healthy persons feces, that is right a poop transplant. But it factor of fecal transplant is a hurdle for some as well as regulatory conundrum of the FDA. Which is why researchers in the university of Guelph Canada came up with synthetic alternative, a laboratory made slurry healthy bacteria they are calling rePOOPulate. The researcher is published in the journal microbiome. It is intend to replace human fecal matter in stool transplants and researchers say has several advantages, the bacteria are carefully controlled and can be tailored to the patient. It reduces the risk of transmitting disease. And well it is just less gross.
