 Bosshard, Zbinden and Altwegg 2002. Type species of the genus.
Description is based on a single isolate.
Gram-positive, irregular and nonbranching rods (0.5-2.0 x 0.7-7.0 µm), occurring in
long chains (up to 30 µm). Nonspore-forming.
Grows on sheep blood, chocolate and Brucella agar, in chopped meat carbohydrate
and thioglycollate. Colonies are nonhemolytic, greyish white , convex, irregular in form
with spresding, undulating margins. Grows at 25-46 ºC, optimum at 37 ºC. Grows in
pH 6.6-7.9, optimum pH 7.5. Strictly anaerobic.
