Desulfomonas pigra
Desulfomonas pigra is a species of sulphate-reducing bacteria (SRB) found in anaerobic environments, including the human gut. It plays a role in sulphur metabolism by reducing sulphate to hydrogen sulphide (H₂S). While hydrogen sulphide is a naturally occurring compound in the colon, elevated levels produced by SRBs like D. pigra can disrupt intestinal barrier function and contribute to gastrointestinal inflammation or discomfort. Increased abundance of Desulfomonas pigra may indicate an overgrowth of sulphur-reducing microbes, potentially associated with diets high in sulphur-containing foods or imbalances in gut microbiota.
Description
It is a sulphate-reducing bacterium in the gut that produces hydrogen sulphide as part of its metabolism.
To assess levels of sulphur-reducing bacteria that may contribute to gut dysbiosis or inflammation.
It may suggest excessive sulphur metabolism in the gut and a possible imbalance in the microbial composition.
In high amounts, it can produce excessive hydrogen sulphide, which may damage the gut lining and promote inflammation.
