Necrotizing enterocolitis (NEC) is the most common and lethal gastrointestinal emergency in premature infants, affecting 5-12% of very low birth weight neonates (<1500 g) with mortality rates of 20-30%. Characterized by intestinal inflammation, necrosis, and perforation…
A chronic inflammatory bowel disease characterized by continuous mucosal inflammation of the colon, extending proximally from the rectum. Unlike crohns disease, UC is limited to the colon, affects only the mucosa/submucosa (not transmural), produces no skip lesions, and…
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…
Cerebral palsy (CP) is the most common motor disability in childhood, affecting 2-3 per 1,000 live births allen 2021 multi organ dysfunction cerebral palsy. Characterized by non-progressive disturbances in movement and posture arising from injury to the developing brain…
Citrobacter is a genus of Gram-negative, facultatively anaerobic bacteria in the Enterobacteriaceae family, named for its ability to utilize citrate as a sole carbon source. Species include C. freundii, C. koseri, and C. rodentium (a mouse model for EHEC infection). In …
Clostridioides difficile is the current NCBI name for NCBITaxon:1496 and the correct, medically recommended combination recorded by LPSN. Both records retain Clostridium difficile as a validly published homotypic synonym of the same organism rather than a separate speci…
Clostridium perfringens is a Gram-positive, strictly anaerobic, spore-forming bacterium infamous for causing gas gangrene, food poisoning, and necrotizing enterocolitis (NEC) in premature infants. It is one of the most widely distributed pathogenic bacteria in nature, f…
A chronic, relapsing-remitting inflammatory bowel disease (IBD) characterized by transmural inflammation of the gastrointestinal tract, most commonly affecting the terminal ileum and colon but capable of involving any segment from mouth to anus zhang 2017 intestinal mic…
This page unifies the infant formula contamination, pregnancy complications, autism spectrum disorder, necrotizing enterocolitis, and neurodevelopmental toxicity threads around a single organizing insight: metal toxicity is disproportionately severe during specific deve…
A Gram-negative obligate anaerobe that occupies a paradoxical niche in the gut microbiota: as a weak butyrate producer (short-chain fatty acid), it has anti-inflammatory potential; as a virulent invasive pathobiont in inflammatory bowel disease (particularly ulcerative …
Alphabetical definitions of specialist terms used throughout this wiki. Where a full concept page exists, the term links to it. --- AhR (aryl hydrocarbon receptor) -- A ligand-activated transcription factor that senses microbial metabolites (especially indoles from tryp…
A Gram-negative, microaerophilic bacterium within the Epsilonproteobacteria (family Helicobacteraceae) that is the primary murine model of hepatobiliary and intestinal disease. Unlike its more famous relative helicobacter pylori, which colonizes the stomach, H. hepaticu…
Hypoxia refers to a state of low oxygen tension (partial pressure of O₂ < 5% in tissue, vs. ~21% in air). In the context of microbiome metallomics, hypoxia is a critical ecological determinant that reshapes bacterial community structure by favoring obligate and facultat…
Interleukin-10 is the primary anti-inflammatory cytokine, produced by Treg cells, macrophages, dendritic cells, and B cells. It suppresses pro-inflammatory cytokine production (IL-6, TNF-alpha, IL-1β), inhibits antigen presentation, and maintains immune tolerance. IL-10…
An umbrella term for chronic relapsing-remitting inflammatory conditions of the gastrointestinal tract, principally crohns disease (CD; transmural, any GI segment) and ulcerative colitis (UC; mucosal, colon only). Approximately 6 million patients worldwide. IBD represen…
Lactobacillus rhamnosus is a Gram-positive, facultatively anaerobic lactic acid bacterium and one of the most extensively studied probiotic species. The GG strain (ATCC 53103), isolated from a healthy human intestinal tract by Gorbach and Goldin in 1983, is the single m…
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 …
See also: saccharomyces (genus page) Saccharomyces boulardii is a non-pathogenic yeast strain used as a probiotic across a wide range of gastrointestinal and inflammatory conditions. Taxonomically a strain of S. cerevisiae, it is phenotypically distinct — optimally acti…
Sphingomonas is a genus of Gram-negative, aerobic, rod-shaped bacteria in the class Alphaproteobacteria, distinguished by the presence of sphingolipids in their outer membrane rather than the lipopolysaccharide (LPS) typical of most Gram-negative bacteria. Originally is…

The virome is the collection of all viruses inhabiting a given ecosystem -- in the gut, this means primarily bacteriophages (phages), which constitute ~90% of the intestinal virome. While microbiome research has historically focused on bacteria, mounting evidence shows …
Zinc is the most widely utilized transition metal cofactor in biology. Approximately 9-10% of the eukaryotic proteome and 5-6% of the bacterial proteome consists of zinc-binding proteins capdevila 2024 bacterial metallostasis sensing trafficking. An estimated one-third …
