'Faecalibacterium' is a genus of bacteria. Its sole known species, 'Faecalibacterium prausnitzii', is an important commensal bacterium of the human gut flora. This bacteria is considered beneficial and is one of the most prevalent intestinal bacterial species in healthy adults. The reduction of this bacteria in the gut (as measured by analyzing bacteria in fecal samples) is seen in several diseases, including Intestinal Bowel Disease (IBD). This bacteria has also been found to be anti-inflammatory. Babies with a higher risk of asthma presented lower levels of four bacteria in their feces samples in comparison with the infants who did not show any symptoms. Those bacteria were identified as Faecalibacterium, Lachnospira, Veillonella and Rothia - known all together as FLVR. A high animal meat, high animal fat, high sugar, highly processed foods, and low fiber diet (the typical westernized diet) lowers F. prausnitzii numbers, while a high-fiber, low meat diet increases F. prausnitzii numbers.Scientists at Catholic University of Louvain in Belgium recently showed that adding inulin, a fermentable fiber, to the diet of obese women increased counts of F. prausnitzii and other clostridial bacteria.
This genus contains microbial species that can reside in the human gastrointestinal tract. [PMC 4262072] Decrease in metabolic disorders.
