Amyloid-Beta Aggregation
The process by which soluble amyloid-beta (Aβ) monomers assemble into neurotoxic oligomers and insoluble fibrillar plaques in the brain -- the defining neuropathological event of alzheimers disease. What distinguishes WikiBiome's treatment of this process from conventio…

Bismuth
A heavy metal traditionally considered safe enough for over-the-counter gastrointestinal remedies (Pepto-Bismol, De-Nol), bismuth is re-emerging as a potent antimicrobial synergist. Its key property: Bi3+ competes with Fe3+ for binding sites on siderophores and bacteria…

Borrelia
A genus of spirochete bacteria transmitted by Ixodes ticks, best known as the causative agent of Lyme disease -- the most common tick-borne illness in the Northern Hemisphere. Borrelia burgdorferi sensu lato comprises approximately 20 genospecies, with B. burgdorferi se…

Copper
An essential trace element with a striking dual nature: required for survival as a cofactor for critical enzymes (SOD1, cytochrome c oxidase, ceruloplasmin), yet toxic in excess through Fenton-like redox cycling and mis metallation of iron-sulfur clusters. Copper is ele…

Desulfovibrionales
An order of Gram-negative, strictly anaerobic sulfate-reducing bacteria (SRB) within the class Deltaproteobacteria. The defining metabolic feature of Desulfovibrionales is dissimilatory sulfate reduction -- using sulfate as a terminal electron acceptor and producing hyd…

Ferritin
The primary intracellular iron storage protein, capable of sequestering up to 4,500 iron atoms in a single molecule as a mineralized ferric oxyhydroxide core. Ferritin is one of the most elegant solutions evolution has produced for the iron paradox: iron is essential fo…

Flavonifractor
A Gram-positive obligate anaerobe in the family Ruminococcaceae (Clostridium cluster IV) whose defining metabolic activity is the degradation of dietary flavonoids — the very polyphenols that serve as anti-inflammatory, antioxidant, and antimicrobial agents. When Flavon…

Gallium
A group 13 post-transition metal (atomic number 31) with no known biological function in any organism — yet one of the most promising antimicrobial metals precisely because of what it cannot do. Ga3+ is nearly identical to Fe3+ in ionic radius (0.62 Å vs 0.645 Å) and co…

Glyoxalase I
The third nickel-dependent enzyme class in human pathogens, after urease and hydrogenase. Glyoxalase I detoxifies methylglyoxal, a reactive and toxic byproduct of glycolysis. While less well-known than urease or hydrogenase as a virulence factor, GloI is emerging as a s…

Hydrogenase
[NiFe] hydrogenases are the second major nickel-dependent virulence factor class in human pathogens. Less widespread than urease but critical for energy metabolism in gastric, enteric, and intracellular pathogens. The discovery that H. pylori hydrogenase powers CagA tra…

Oxidative Stress
Oxidative stress is the imbalance between the production of reactive oxygen and nitrogen species (ROS/RNS) and the capacity of biological antioxidant defense systems to detoxify them. It is the single most commonly invoked mechanism across metal toxicology in this wiki,…

Urease
The most widespread nickel-dependent virulence factor across human pathogens. Urease is found in at least 40 prokaryotic and 9 eukaryotic pathogenic species, making it the single most important enzyme linking dietary/environmental nickel to infectious disease.
