Desulfovibrio piger
Desulfovibrio piger is a common sulphate-reducing bacterium (SRB) in the human gut microbiota. It reduces sulphate and other sulphur compounds into hydrogen sulphide (H₂S), a gas that in small amounts plays physiological roles but in excess can be toxic to intestinal cells. Elevated levels of D. piger have been associated with gastrointestinal disorders such as inflammatory bowel disease (IBD) and irritable bowel syndrome (IBS). Its abundance may reflect increased sulphur intake through diet or a disrupted microbial balance that favours sulphur metabolism.
Description
It is a type of sulphur-reducing bacterium found in the gut that converts sulphate into hydrogen sulphide.
To evaluate sulphur metabolism and potential microbial imbalances linked to gut inflammation or dysbiosis.
An overgrowth of sulphur-reducing bacteria, which may lead to excessive hydrogen sulphide production and intestinal irritation.
While it is a normal resident of the gut, elevated levels may contribute to impaired gut barrier function and inflammation.
