A Gram-negative, obligate anaerobic genus within the family veillonellaceae (class Negativicutes, phylum Firmicutes) defined by its specialized amino acid fermentation -- the genus name literally means "acid from amino acids." Acidaminococcus ferments glutamate as its p…
A genus of Gram-positive obligate anaerobes in the family Lachnospiraceae (Clostridium cluster XIVa) that occupy a critical metabolic relay position in gut ecosystem stability: converting lactate to butyrate. Anaerostipes is one of the most consistently depleted genera …
A class of Gram-negative bacteria within the phylum Proteobacteria that has emerged as a causal risk factor for schizophrenia and bipolar disorder through Mendelian randomization studies. Betaproteobacteria includes genera with notable metal tolerance -- particularly wi…
Bifidobacteriaceae is the family containing bifidobacterium and related genera (alloscardovia). It is the dominant family in the healthy infant gut and a significant commensal family in adults. Family-level depletion is documented in ASD (marked reduction of Actinobacte…
Bifidobacterium bifidum is an obligate anaerobic, Gram-positive species that specializes in human milk oligosaccharide (HMO) and mucin glycan degradation. It is one of the earliest colonizers of the infant gut and a widely used probiotic species.
Bifidobacterium breve is a Gram-positive, obligate anaerobic species within the phylum Actinobacteria, predominantly found in the infant gut and breast milk. It is among the earliest colonizers of the neonatal intestine and plays a key role in human milk oligosaccharide…
This knowledge-base record is being expanded from WikiBiome’s evidence graph.
A class of Gram-positive, obligate anaerobic bacteria within the phylum Firmicutes that represents the most functionally diverse and clinically significant taxonomic class in the human gut microbiome. Clostridia encompasses the dominant butyrate producers sustaining col…
An order of Gram-positive, obligate anaerobic bacteria within the class clostridia (phylum Firmicutes) that represents the single most functionally important taxonomic group in the human gut. Clostridiales encompasses the major butyrate-producing families (lachnospirace…
Lachnoclostridium is a genus of obligate anaerobic, Gram-positive bacteria in the lachnospiraceae family. It is a butyrate-producing commensal with emerging clinical significance as a treatment response biomarker and diagnostic marker.
Lachnospira is a genus of Gram-positive, obligate anaerobic bacteria within the lachnospiraceae family (Firmicutes phylum). L. pectinoschiza, the type species, is a specialist pectin fermenter that produces short chain fatty acids from plant-derived polysaccharides. The…
Lactobacillaceae is the family containing the genus lactobacillus and related genera. It is the dominant family in the healthy vaginal microbiome and a significant family in the gut. Family-level depletion is reported across schizophrenia szeligowski 2020 gut microbiome…
Lactobacillus acidophilus is one of the most widely used probiotic species, with clinical trial evidence spanning multiple conditions. It is a component of many multi-strain probiotic formulations and has been tested in RCTs for schizophrenia, breast cancer chemotherapy…
Lactobacillus plantarum is one of the most versatile probiotic species — found in fermented foods (kimchi, sauerkraut, sourdough), the human gut, and the vaginal microbiome. It has the largest genome among Lactobacillus species (~3.3 Mb), encoding extensive stress toler…
Paraprevotella is a genus of obligate anaerobic, Gram-negative bacteria in the family Prevotellaceae, related to prevotella. It is a gut commensal with emerging associations across neuropsychiatric and reproductive conditions. - Schizophrenia: Altered in gut-brain axis …
A Gram-negative, obligate anaerobic genus within the Firmicutes phylum (family Acidaminococcaceae, class Negativicutes). The primary species P. faecium and the recently characterized P. succinatutens are specialized propionate producers that utilize succinate as their m…
A family of Gram-negative, obligate anaerobic bacteria within the phylum Bacteroidota (formerly Bacteroidetes) that includes the genus prevotella and the recently described alloprevotella. Prevotellaceae are specialist fiber fermenters producing short-chain fatty acids,…
A filamentous fungus in the order Hypocreales (family Ophiocordycipitaceae), historically studied as an insect and nematode pathogen (P. lilacinum, formerly Paecilomyces lilacinus), now emerging as a clinically significant protective member of the gut mycobiome — and it…
Rikenella is a genus of obligate anaerobic, Gram-negative bacteria in the family Rikenellaceae (phylum Bacteroidetes). The primary species is R. microfusus. In the WikiBiome vault, Rikenella is consistently depleted across disease states — a protective commensal whose l…
A genus of Gram-negative, crescent-shaped, strictly anaerobic bacteria found in both the oral cavity and the gastrointestinal tract. Selenomonas species are characterized by their distinctive morphology -- a curved rod with a tuft of flagella arising from the concave si…
A family of Gram-negative, obligate anaerobic bacteria within the Firmicutes phylum (class Negativicutes) that occupies a unique metabolic niche as specialized lactate utilizers. Veillonellaceae cannot ferment sugars directly -- instead, they cross-feed on lactate produ…
