A genus of Gram-positive, facultatively anaerobic, filamentous bacteria that are among the most abundant colonizers of the human oral cavity. Actinomyces species, particularly A. naeslundii, play dual roles as early dental plaque colonizers and as opportunistic pathogen…
Alloprevotella is a genus of Gram-negative, obligate anaerobic bacteria within the family Prevotellaceae that represents a distinct clade from prevotella with specific protective roles in type 2 diabetes prevention and metabolic health. Alloprevotella depletion is one o…
A genus of Gram-positive, strictly anaerobic, butyrate-producing bacteria in the order Clostridiales (phylum Firmicutes). The type species, Butyricicoccus pullicaecorum, was originally isolated from chicken caecal content but has since been identified as a significant m…
Cerebral palsy (CP) is the most common motor disability in childhood, affecting 2-3 per 1,000 live births allen 2021 multi organ dysfunction cerebral palsy. Characterized by non-progressive disturbances in movement and posture arising from injury to the developing brain…

An order of Gram-negative, obligate anaerobic bacteria within the phylum Fusobacteriota (formerly Fusobacteria). This order-level page covers the broader taxonomic group that includes the well-characterized genus fusobacterium and its key species fusobacterium nucleatum…
A Gram-negative, obligate anaerobic bacterium that has emerged as the most consistently CRC-associated microorganism in human gut microbiome studies. F. nucleatum is the primary species of concern, originally a commensal of the oral cavity that translocates to colorecta…
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…
Haemophilus is a genus of small, Gram-negative, facultatively anaerobic coccobacilli that inhabit the upper respiratory tract, oral cavity, and gastrointestinal tract. The genus name literally means "blood-loving" -- a direct reference to its absolute requirement for he…
A genus of lipophilic basidiomycete yeasts that is the dominant fungus on human skin and has recently been recognized as a significant component of the gut mycobiome. M. restricta, M. globosa, and M. furfur are the primary species. Originally studied as the cause of dan…

A Gram-positive, obligate anaerobic genus that has emerged as one of the most consistently enriched taxa in colorectal cancer. The key pathogenic species P. anaerobius promotes colorectal carcinogenesis through multiple mechanisms including cholesterol biosynthesis indu…
A Gram-negative, obligate anaerobic genus with the keystone pathogen P. gingivalis at its center. Named for its porphyrin (heme) requirement, Porphyromonas is the prototypical periodontal pathogen and one of the most important organisms connecting oral health to systemi…
A Gram-negative, obligately anaerobic, black-pigmented bacterium and one of the classical periodontopathogens. P. intermedia belongs to the "orange complex" of periodontal pathogens (Socransky classification) and is distinguished by its iron and heme dependency -- the c…
Rothia is a genus of Gram-positive, facultatively anaerobic bacteria in the family Micrococcaceae (phylum Actinobacteria). The most commonly identified species in microbiome studies are Rothia dentocariosa and Rothia mucilaginosa, both of which are primary inhabitants o…
A severe neuropsychiatric disorder affecting approximately 1% of the global population, characterized by positive symptoms (hallucinations, delusions), negative symptoms (anhedonia, social withdrawal, flat affect), and cognitive deficits. Life expectancy is reduced by 1…
A genus of Gram-positive facultative anaerobes that occupy niches ranging from benign commensals (dental plaque, skin) to acute pathogens (pharyngitis, impetigo, invasive disease). Streptococci are uniquely manganese-dependent for catalytic scavenging of reactive oxygen…

A Gram-negative, obligate anaerobic genus within the Firmicutes phylum (class Negativicutes, family Veillonellaceae). The primary species V. parvula is a specialized lactate utilizer that occupies a unique metabolic niche by cross-feeding with lactate-producing bacteria…
