A Gram-negative, aerobic, non-fermenting coccobacillus and a member of the ESKAPE group of priority pathogens (Enterococcus, Staphylococcus, Klebsiella, Acinetobacter, Pseudomonas, Enterobacter). Acinetobacter baumannii is among the most problematic nosocomial pathogens…
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 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…
Gemella is a genus of Gram-positive, facultatively anaerobic cocci that are normal commensals of the oral cavity. Species include G. morbillorum, G. haemolysans, and G. sanguinis. In the WikiBiome context, Gemella is notable for its oral-gut translocation pattern — an o…
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…
Penicillium is a genus of filamentous fungi best known as the source of penicillin. In the WikiBiome context, Penicillium appears in the gut mycobiome — the fungal component of the microbiome — with associations across ASD, pancreatitis, and cardiometabolic disease.
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,…
Ralstonia is a genus of Gram-negative, aerobic bacteria in the class Betaproteobacteria. While Wikipedia focuses on R. solanacearum (a plant pathogen), the WikiBiome-relevant species are R. pickettii and R. metallidurans (now Cupriavidus metallidurans) — organisms with …
A genus of Gram-positive, obligate anaerobic cocci within the Firmicutes phylum that exemplifies dual-nature microbiology — containing both keystone beneficial species and disease-associated pathobionts within the same genus. The genus spans multiple former taxonomic gr…
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…
A Gram-negative, microaerophilic genus within the Proteobacteria phylum (family Sutterellaceae). The primary species S. wadsworthensis is classified as a pathobiont due to its IgA-degrading capacity and associations with neurodevelopmental and inflammatory conditions. H…
A Gram-positive, facultatively anaerobic genus within the class Erysipelotrichia (phylum Firmicutes) that has become one of the most frequently identified taxa in gut-brain and gut-immune Mendelian randomization studies. Turicibacter sanguinis, the type species, possess…
