Bifidobacteria
Bifidobacteria are gram-positive, anaerobic bacteria that are ubiquitous in a healthy gastrointestinal tract. They are protective against intestinal permeability.
Decreased populations of bifidiobacteria have been associated with vitamin K deficiency,[1] atopic diseases,[2] irritable bowel syndrome,[3] and autism.[4][5]
Chronic fatigue syndrome[edit | edit source]
Bifidobacteria have been shown to be reduced in CFS patients.[6]
One study found that 6-8 weeks of Bifidobacterium infantis supplementation reduced C-reactive protein, TNF-alpha and IL-6 levels in CFS patients.[7] Another found that B. infantis boosted serotonin levels in the brain.[citation needed]
FUT2[edit | edit source]
Fucosyltransferase 2 enzyme (FUT2) is an enzyme related to intestinal dysbiosis. People who are genetic non-secretors of FUT2 have reduced diversity, richness, and abundance of bifidobacteria.[8]
