Belongs to the cultivable cluster of the phylum "Synergistetes" and related to Jonquetella anthropi [1].

After 7-day incubation on Fastidious Anaerobe Agar plates (incorporating 5 % horse blood), strains of this species form circular, entire, high convex colonies around 1 mm in diameter.

Gram-negative, obligately anaerobic, cocco-bacilli to short bacilli. Strains are asaccharolytic and generally biochemically unreactive although hydrogen sulphide is produced. Acetic and isovaleric acids and minor to trace amounts of propionic, isobutyric, succinic and phenyl-acetic acids are produced as end products of fermentation. The G + C content of the DNA of the type strain is 59 mol %.

Found in the human mouth and vagina.

Has been isolated from dvanced dental caries, acute dentoalveolar infections and subgingival plaque in periodontitis.
