Hierarchy Structure:
General Information:
Member of one of the 10 phylogenetic groups of oral treponemes [1,4]. Originally detected in subjects with periodontitis as not-yet-cultivated phylotype (Group IV) termed
Treponema
sp. IV:17C:GF6 [4]. Closest cultivable relative is
Treponema maltophilum,
which also falls in Group IV.
Cultivability:
Growth on OMIZ-Pat-w/oPC agarose [1], are off-white, diffuse (~3 mm), subsurface colonies after 7 days incubation at 37
o
C. Will not grow in chemically defined media, e.g., OMIZ-W1 [1], but requires yeast extract or Neopeptone
Phenotypic Characteristics:
Obligately anaerobic, catalase negative, helically coiled with translational motility in broth, especially in media of high viscosity [1]. Will creep on solid surfaces, such as agar media or glass. Cells are Gram-negative, 0.15 um by 5 um, with a 1-2-1 periplasmic flagellar arrangement.
N-acetylglucosamine is required for growth, and D-arabinose, L-fucose or D-ribose enhance growth. Other carbohydrates do not appear to support growth. Lecithin and 1% fetal calf serum inhibits growth. Strains are resistant to rifampicin and fosfomycin.
High activities for alkaline phosphatase, acid phosphatase, B-galactosidase, B-glucuronidase, N-acetyl-B-glucosaminidase, phospholipase A, and phospholipase C
Prevalence and Source:
Detected in human subgingival plaque, most often in subjects with periodontitis
Disease Associations:
Association (e.g. diseased vs control sites) in patients with adult periodontitis and rapidly progressive periodontitis [1,3] and endodontic lesions [2]. Strong activities of phospholipase A and phospholipase C may serve as potential virulence factors [1]
