Bilophila wadsworthii

Bilophila wadsworthii is a gram-negative, anaerobic, sulphur-reducing bacterium commonly found in the human gut in small amounts. It is capable of metabolising bile acids and reducing sulphur compounds to hydrogen sulphide (H₂S), a gas that in excessive amounts can be toxic to gut epithelial cells and disrupt intestinal integrity. Elevated levels of Bilophila wadsworthii have been associated with inflammatory conditions such as colitis and may indicate a dysbiotic gut environment, especially in response to high-fat or high-animal protein diets. This bacterium is considered a potential pathobiont due to its ability to promote inflammation under certain conditions.
