Fecal microbe transplants: B. vulgatus genes that correlate with early colonization

Fecal microbe transplants from healthy donors can treat patients with recurrent Clostridium difficile infections. However, after tens of thousands transplants, little was known about which donor strains provide long-term engraftment, and which engraft early after the transplant. Most failures of fecal microbe transplantation occur in the first four weeks. Researchers have now found 19 Bacteroides vulgatus genes that were unique to three strains that show early engraftment in patients after a fecal transplant, as opposed to seven strains that did not show early engraftment.
