Aerococcus is a genus of Gram-positive, alpha-hemolytic, catalase-negative cocci. The primary species of clinical relevance are A. urinae (a cause of urinary tract infections, particularly in elderly men) and A. christensenii (a vaginal commensal). In the WikiBiome vaul…

Alloscardovia is a genus of anaerobic, Gram-positive bacteria in the family Bifidobacteriaceae (phylum Actinobacteria). The primary species is A. omnicolens, which colonizes the human urogenital tract. In the WikiBiome vault, Alloscardovia appears exclusively in endomet…
Anaerococcus is a genus of Gram-positive, obligate anaerobic cocci within the phylum Firmicutes. It is a normal inhabitant of the human vaginal, skin, and gastrointestinal microbiota, but is recognized as an opportunistic pathogen in dysbiotic states, particularly when …
Atopobium is a genus of obligate anaerobic, Gram-positive bacteria in the phylum Actinobacteria. The primary species of clinical relevance is A. vaginae (recently reclassified as Fannyhessea vaginae), which is one of the hallmark organisms of bacterial vaginosis (BV) an…

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…

Gardnerella vaginalis is a Gram-variable, facultatively anaerobic bacterium that is the key organism in bacterial vaginosis (BV), the most common vaginal infection in women of reproductive age. Its sialidase production, biofilm-forming capacity, and associations with he…

Lactobacillus iners is a Gram-positive, facultatively anaerobic bacterium that dominates the vaginal microbiome of many women worldwide, defining Community State Type III (CST-III) in vaginal microbiome classification. For decades, all vaginal Lactobacillus species were…
Megasphaera is a genus of obligate anaerobic, Gram-negative bacteria in the family Veillonellaceae (class Negativicutes, phylum Firmicutes). The genus occupies two distinct ecological niches — the vaginal microbiome (where it is a hallmark of bacterial vaginosis) and th…
See also: porphyromonas (genus page), porphyromonas gingivalis (species page) Porphyromonas bennonis is an obligate anaerobic, Gram-negative bacterium related to the periodontal pathogen porphyromonas gingivalis. Unlike its oral relative, P. bennonis is primarily associ…

Sneathia is a genus of obligate anaerobic, Gram-negative bacteria in the phylum Fusobacteriota (formerly Fusobacteria). The primary species is S. sanguinegens (formerly Leptotrichia sanguinegens), with S. amnii also clinically significant. Sneathia is a member of the BV…
