Faecalibacterium prausnitzii

Faecalibacterium prausnitzii is an important single bacterial species that has been discoved in recently. Its abundance in a healthy gut is significant, roughly 10-15%. Low numbers of Faecalibacterium prausnitzii have been linked to inflammatory gut conditions and its numbers in many gut disorders such as Crohn´s disease, IBD and celiac disease has decreased.

It has also been shown that overweight individuals with elevated visceral fat have low numbers of Faecalibacterium prausnitzii. This is linked to low-grade inflammation in the gut of overweight individuals.

Butyric acid produced by faecalibacteria improves the gut villus condition and prevents a leaky gut and therefore protects the gut from inflammation. Butyric acid has also been linked to satiety and blood sugar regulation.

Faecalibacteria cannot be produced in the same way as bifidobacteria and lactobacilli. They are demanding and only thrive in the anaerobic conditions of the gut. It has been shown that growth and activity of the faecalibacteria can be improved with bifidobacteria and xylo-oligosaccharide fibers.
