The study looked at the gut bacteria of people with ulcerative colitis by comparing poop and colon tissue samples. They found more types of bacteria in colon tissue than in poop, and some bacteria were only in colon tissue. While poop samples are easier to get, colon tissue gives a better picture of the bacteria when studying this disease.
