• Ulcerative colitisRelated: Microbial differences are studied as possible contributors to disease onset and persistence.

• Fecal microbiota transplantationNarrower topic: The transplant introduces a community into this ecosystem, aiming to restore its composition and function.

• Gut-brain axisRelated: Microbes produce metabolites and other signals that can affect gut and brain physiology.

• NutritionRelated: Microbial variation may help explain why people respond differently to the same diet.

• Bariatric surgeryRelated: Surgery changes the gut environment, and researchers study how microbial shifts relate to outcomes.

• ColonRelated: Colonic microbes ferment material that escapes digestion in the small intestine.

• FecesRelated: Microbes make up a substantial part of fecal material and transform intestinal contents.

• TrophallaxisRelated: In some social insects, trophallaxis transfers microbes that help digest food.
