Ileostomy patients harbor different gut microbes

UPI reports that researchers from the University of California-Davis and Georgetown University Medical Center studied bacterial DNA in patients with an ileostomy -- an opening into their small bowel -- and patients with closed ileostomies.

The research team found in ileostomy patients, the gut bacteria were mostly lactobaccilli and enterobacteria -- bacteria that can use oxygen in their metabolism. But in patients whose ileostomies had been closed, the bacterial population was made up mostly of bacteroides and clostridia -- bacteria to which oxygen is toxic.

In their study, the researchers were able to follow changes in the gut bacteria of 17 transplant patients for up to two years by taking periodic samples from the small bowel through the ileostomy opening.
