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, irritable bowel syndrome, and autism. (more...)

Dysbiosis is an imbalance in the microbial ecology of a part of the body, usually the gut. There is strong evidence that dysbiosis or an imbalance in the microbial ecology of the gut plays a role in the symptoms of ME/CFS. (more...)

Small intestinal bacterial overgrowth (SIBO) is an excessive bacterial growth in the small intestine which in contrast to the large intestine in healthy individuals contains relatively small populations of bacteria. There is some evidence of high rates of SIBO among ME/CFS and fibromyalgia patients. (more...)

Escherichia coli is a Gram-negative, facultatively anaerobic, rod-shaped bacterium of the genus Escherichia that is commonly found in the lower intestine. Most strains are harmless. ME/CFS patients have E. coli levels that are only 20% of a normal. E. coli bacteria create essential precursors to many important nutrients and compounds, including Folic acid, CoQ10, and Vitamin K.

The microbiome is the ecological community of commensal, symbiotic and pathogenic microorganisms that live on the skin and genitals and in the nose, ears, mouth and gut. Dysbiosis or an imbalance in this community may play a role in the pathophysiology of chronic fatigue syndrome. (more...)
