In one study, for example, Slovenian vegans had a higher ratio of the bacterium Faecalibacterium
prausnitzii in their guts (Matijasic et al.
For example, Faecalibacterium
prausnitzii has recently been identified as an important gut bacterium that may be associated with Crohn's Disease.
The main dominant genera however changed after ginseng intake with Blautia, Bifidobacterium and Anaerostripes dominant prior to the intervention, whereas Bifidobacterium, Blautia and Faecalibacterium
were most abundant after intervention.
We identified several decreased Firmicutes families following arsenic exposure, and a number of Firmicutes species, such as Eubacterium, Faecalibacterium
, and Roseburia, are known to be butyrate producers (Tremaroli and Backhed 2012).
It was shown that the abundance of butyrate-producing Faecalibacterium
prausnitzii species is negatively associated with biomarkers of inflammation before and after RYGB, indicating that this bacterial species may contribute to maintaining a healthy gut (48).
populations rose in the groups consuming both types of fiber.
Trials in mice have shown that injecting one such strain Faecalibacterium
prausnitzii into the digestive tract is effective at restoring normal levels of gut bacteria and treating the symptoms of IBD.
Analysis of the participants' feces showed that Bifidobacterium, Clostridium lituseburense and Faecalibacterium
prausnitzii populations decreased following the gluten free diet, while populations of Enterobacteriaceae and Escherichia coli increased.
Now a French team has highlighted the bug, Faecalibacterium
prausnitzii, which they show secretes biochemicals that reduce inflammation.
It may be that IBD is triggered or aggravated by the lack of important immunomodulating organisms such as Faecalibacterium
prauznitzii that FMT replaces.
In lane H, a new band 25 related to Faecalibacterium
prausnitzii was found as compared to the other 4 groups.
Floch noted that the gut microbiota is abnormal in IBD, with reduced populations of Faecalibacterium
prausnitzii and increased numbers of Escherichia coli.
