All are anaerobic, gram-positive, non-saccharolytic rods. They are differentiated from each other and from other non-saccharolytic species of eubacteria by acid and gas products in broth cultures and by morphological and growth characteristics. The type strains for the species are as follows: E. timidum ATCC 33093; E. brachy, ATCC 33089; and E. nodatum, ATCC 33099. These species were detected in 35 to 42% of the subgingival samples examined and, where present, constituted 3 to 57% of the cultivable flora. Strains of these species were isolated only occasionally from the adjacent supragingival areas sampled.", }
