Alistipes
A Gram-negative, obligate anaerobic genus within the Bacteroidetes phylum (family Rikenellaceae). Alistipes occupies a complex and context-dependent role in the gut ecosystem — some species carry well-documented anti-inflammatory properties, while the genus is paradoxic…

Bacteroidaceae
Bacteroidaceae is a family of obligate anaerobic, Gram-negative bacteria in the order bacteroidales. The dominant genus is bacteroides, which includes B. fragilis, B. vulgatus, B. thetaiotaomicron, and B. uniformis. Bacteroidaceae are among the most abundant gut bacteri…

Barnesella
Barnesella is a genus of obligate anaerobic, Gram-negative bacteria in the phylum Bacteroidetes. It is a relatively understudied gut commensal that appears in the WikiBiome vault primarily in the context of endometriosis microbiome studies, where it is part of the compl…

Barnesiella
Barnesiella is a genus of Gram-negative, obligate anaerobic bacteria within the phylum Bacteroidetes. It is a commensal member of the healthy human gut microbiota, recognized for its role in colonization resistance — the ability of the resident microbiome to prevent est…

Butyricimonas
A Gram-negative, obligate anaerobic genus within the Bacteroidetes phylum (family Odoribacteraceae). Despite its relatively recent characterization, Butyricimonas has gained significant attention as a member of the protective butyrate-producing consortium that is consis…

Dysbiosis
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…

Gut Microbiome
The community of trillions of microorganisms — bacteria, archaea, fungi (mycobiome), viruses, and bacteriophages — inhabiting the human gastrointestinal tract, with the highest density in the colon (~10¹¹ cells/g). The gut microbiome encodes 100–150 times more genes tha…

Parabacteroides
A Gram-negative, obligate anaerobic genus within the Bacteroidetes phylum, closely related to bacteroides fragilis. The best-characterized species, P. distasonis, has emerged as a key anti-inflammatory commensal with significant roles in bile acid metabolism and metabol…

Phocaeicola
A Gram-negative, obligate anaerobic genus within the phylum Bacteroidota (formerly Bacteroidetes) that was recently reclassified from Bacteroides based on phylogenomic evidence (Garcia-Lopez et al., 2019). The key species -- Phocaeicola vulgatus (formerly Bacteroides vu…

Prevotella
A Gram-negative, obligate anaerobic genus within the Bacteroidetes phylum that exemplifies context-dependent microbiome effects -- beneficial in some settings, pathogenic in others. P. copri is the dominant species in the human gut and a hallmark of plant-rich, fiber-ri…

Propionic Acid
A three-carbon short-chain fatty acid (SCFA) produced primarily by Bacteroidetes and certain Firmicutes through anaerobic fermentation of dietary substrates. At physiological concentrations in healthy gut microbiomes, propionic acid (PPA) is a normal fermentation produc…
