Isolated from Human Periodontitis JF International Journal of Systematic and Evolutionary Microbiology, VO 30 IS 1 SP 163 OP 169 DO https://doi.org/10.1099/00207713-30-1-163 PB Microbiology Society, SN 1466-5034, AB Three new species of Eubacterium, E. timidum, E. brachy, and E. nodatum, which were isolated principally from subgingival areas associated with periodontitis, are described. 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., UL https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/00207713-30-1-163
