Bilophila wadsworthii is a gram-negative, anaerobic, sulfur-reducing bacterium commonly present in small quantities within the human gut. It can metabolize bile acids and reduce sulfur compounds to hydrogen sulfide (H₂S), a gas that, in excessive amounts, can be toxic to gut epithelial cells and compromise intestinal integrity. Increased levels of Bilophila wadsworthii have been linked to inflammatory conditions such as colitis and may signal a dysbiotic gut environment, particularly in response to high-fat or high-animal protein diets. This bacterium is regarded as a potential pathobiont due to its capacity to induce inflammation under certain circumstances.
It is a sulfur-reducing bacterium in the gut microbiome that metabolizes bile and produces hydrogen sulfide gas.
To evaluate the presence of sulfur-reducing bacteria, which can affect gut health and inflammation.
It could indicate an imbalance in gut bacteria, excessive sulfur consumption, or inflammation within the digestive system.
If present in large amounts, it may cause damage to the mucous membranes and inflammation, especially in individuals who are more vulnerable or consume diets rich in fat and sulfur.
