Gram-positive small, elliptical (central swellings may occur), rods, occurring singly, in
pairs and in short chains. Non-motile.
Colonies are raised or low convex, translucent to transparent, 1-2 mm in diameter
after 5 days of anaerobic incubation at 37 ºC on BH blood agar. Growth is stimulated
by 0.02% Tween 80 and usually is stimulated by 10% rabbit serum. Variable growth at
45 ºC. Optimum growth at 37 ºC. No growth in 6.5% NaCl. Strict anaerobic.
Isolated from human gingival crevices, especially in patients with periodontitis.
Undetermined. Isolated from patients with periodontitis.

Positive results for ammonia produced from arginine, fermentation of fructose, glucose, maltose, mannose, sucrose, and trehalose.

Negative results for catalase, gelatin liquefaction, hippurate hydrolysis, indole production, nitrate reduction, fermentation of amygdalin,
erythritol, esculin, glycerol, inositol, lactose, mannitol, melezitose, melibiose, raffinose, rhamnose, sorbitol, starch, and xylose.

Variable results for starch hydrolysis, esculin hydrolysis, fermentation of arabinose, cellobiose, inulin, ribose, and salicin.
