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…
Christensenellaceae is a family of Gram-negative, strictly anaerobic bacteria within the order Clostridiales (phylum Firmicutes) that has emerged as one of the most consistently health-associated and heritable members of the human gut microbiome. First formally describe…
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 …
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…

Odoribacter splanchnicus is a Gram-negative, obligate anaerobic bacterium belonging to the family Odoribacteraceae within the phylum Bacteroidota (formerly Bacteroidetes). It is a commensal resident of the human colon recognized primarily as a producer of short chain fa…
An order of Gram-positive, obligate anaerobic bacteria within the class Clostridia (phylum Firmicutes) that has emerged as one of the most consistent markers of a healthy gut ecosystem. Oscillospirales members are butyrate producers associated with leanness and metaboli…
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 Gram-negative obligate anaerobe that occupies a unique context-dependent niche in the human gut microbiome. P. copri is significantly enriched in rheumatoid arthritis patients and is associated with metabolic syndrome and obesity, yet in other contexts it can function…
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,…
