chains. Non-spore-forming.
Colonies are white, convex, undulate and pointy after a night at 37 ºC under anaerobic
conditions on MRS agar. Grows at 20-45 ºC (optimum 37 ºC), at pH 4.5-8.5 (optimum
pH 7.0) and in 0-4.0% NaCl (optimum 0% NaCl). Grows in a microaerobic atmosphere
with 5.0% CO2, but also in anaerobic or aerobic atmospheres

pH 7.0) and in 0-4.0% NaCl (optimum 0% NaCl). Grows in a microaerobic atmosphere

Isolated from the female reproductive tract.
Due to its limited carbon source usage, it can be considered a very host-adapted species.
