Non-digestible food substrates that selectively stimulate the growth and/or activity of beneficial gut microorganisms, conferring health benefits to the host. Distinct from probiotics (live organisms) and postbiotics (microbial metabolic products), prebiotics act as fue…

A Gram-negative obligate anaerobe that exemplifies the commensal-pathobiont spectrum. B. vulgatus is a common component of the healthy gut microbiota, yet is significantly enriched in colorectal cancer and depression, suggesting a context-dependent pathogenic potential.…
Berberine is an isoquinoline alkaloid from traditional Chinese medicine (Coptis chinensis, Berberis species) that acts as a prebiotic microbiome modulator rather than a direct antimicrobial at gut-relevant concentrations. It is discussed across 16+ sources in the WikiBi…

Disruption of the normal composition and metabolic function of microbial communities, particularly the gut microbiome. In the metallomics context, dysbiosis is both a consequence of metal toxicity and an amplifier of further disease -- creating vicious cycles where meta…
Endometriosis is a chronic estrogen-dependent inflammatory condition affecting approximately 10% of reproductive-age women, characterized by the growth of endometrial-like tissue outside the uterus colonetti 2023 gut vaginal microbiota endometriosis meta analysis. The c…
The transfer of processed stool from a healthy donor into a recipient's gastrointestinal tract to restore a disrupted microbial community. FMT is the most direct form of microbiome intervention -- replacing the entire community rather than supplementing individual strai…
Human milk oligosaccharides are a diverse family of over 200 structurally distinct complex sugars found in breast milk. They are the third most abundant solid component of human milk (after lactose and lipids), yet they are not digestible by the infant. Their sole purpo…
Multi-strain synbiotic supplementation (probiotic + prebiotic) as adjunctive therapy alongside antipsychotics. This is the strongest validated microbiome-targeted intervention for schizophrenia, with both psychiatric symptom improvement and metabolic benefit demonstrate…
A family of Gram-positive obligate anaerobes (formerly classified as the genus Oscillospira, now reclassified into Oscillibacter and related genera within Oscillospiraceae) that serve as keystone butyrate producers in the healthy human distal colonic microbiota (Konikof…
Pancreatitis is inflammation of the pancreas, occurring in acute (AP) and chronic (CP) forms. Acute pancreatitis ranges from mild self-limiting disease to severe necrotizing pancreatitis with 20-30% mortality. Chronic pancreatitis is a risk factor for pancreatic cancer …
The second most common neurodegenerative disease, affecting over 10 million people worldwide dorsey 2018 parkinsons incidence meta analysis. Characterized by progressive loss of dopaminergic neurons in the substantia nigra, alpha-synuclein aggregation (Lewy bodies), and…
Polyphenols are a diverse class of plant-derived compounds characterized by multiple phenol structural units. They are among the most abundant antioxidants in the human diet, found in fruits, vegetables, tea, coffee, wine, chocolate, and spices. What makes polyphenols p…
A Gram-negative obligate anaerobe that occupies a unique context-dependent niche in the human gut microbiome. P. copri is significantly enriched in rheumatoid arthritis patients and is associated with metabolic syndrome and obesity, yet in other contexts it can function…
Ruminococcus bromii is a Gram-positive, obligate anaerobic bacterium within the ruminococcaceae family and the primary keystone degrader of resistant starch in the human gut. Without R. bromii, the microbial community cannot efficiently access resistant starch types RS2…
A Gram-positive obligate anaerobe that has emerged as a pro-inflammatory pathobiont enriched across multiple disease states including crohns disease, depression, and multiple sclerosis. R. gnavus produces a species-specific inflammatory polysaccharide that activates int…
A synbiotic is a combination of a probiotic (live beneficial microorganism) and a prebiotic (substrate that selectively feeds beneficial microbes), designed to work synergistically — the prebiotic supports the survival and colonization of the probiotic organism. Synbiot…
A synbiotic is a combination of live microorganisms (probiotics) and substrates selectively utilized by host microorganisms (prebiotics) that confers a health benefit. The rationale is additive or synergistic: the prebiotic component (typically inulin, fructo-oligosacch…
Type 2 diabetes (T2D) is a metabolic disease characterized by insulin resistance and progressive beta-cell dysfunction, affecting over 500 million people worldwide (IDF Diabetes Atlas 2021). The conventional framing centers on caloric excess and sedentary behavior. The …
