Genetics of Treponema: characterization of Treponema hyodysenteriae and its relationship to Treponema pallidum [PDF]
Infection and Immunity, 1978 Saturation reassociation assays with 125I-labeled treponemal DNAs show that Treponema hyodysenteriae is genetically unrelated to T. pallidum (Nichols), T. phagedenis biotype Reiter, and T. refringens biotype Noguchi. Pathogenic and nonpathogenic isolates of T. hyodysenteriae exhibited 28% sequence homology and had an extremely low guanine-plus-cytosine

NOTES ON THE CULTIVATION OF TREPONEMA PALLIDUM [PDF]
Journal of Experimental Medicine, 1915 We consider themost importantcontribution reported in this paper the fact that Treponema pallidum can be cultivated in fluid media, without the addition of agar, together with tissues sterilized by heat. This forms an excellent method of obtaining mass cultures for luetin preparation and immunological experimentation.

In Vitro Cultivation of the Syphilis Spirochete Treponema pallidum
Current Protocols, 2021 For over a century, investigation of Treponema pallidum subsp. pallidum, the spiral‐shaped bacterium that causes syphilis, was hindered by an inability to culture the organism in vitro. A recent breakthrough has enabled continuous in vitro growth of this

Genetic engineering of Treponema pallidum subsp. pallidum, the Syphilis Spirochete
bioRxiv, 2021 Background Despite more than a century of research, genetic manipulation of Treponema pallidum subsp. pallidum (T. pallidum), the causative agent of syphilis, has not been successful.

Detection of treponemes in digital dermatitis lesions of captive European bison (Bison bonasus)
PLoS ONE, 2021 A newly-discovered foot disease of unknown origin in captive European Bison (Bison bonasus) was recently detected at Berne Animal Park. Dermatitis of the interdigital cleft of varying degrees of severity was diagnosed in all animals (n = 10).

Syphilis: an atypical case of sepsis and multiple anogenital lesions in secondary syphilis [PDF]
Journal of Community Hospital Internal Medicine Perspectives, 2016 The incidence of syphilis has historically been cyclical in nature, often in relation to the rise and fall of public health initiatives directed toward eradication along with social attitudes toward sexual practices.

Lipooligosaccharides from Treponema hyodysenteriae and Treponema innocens [PDF]
Infection and Immunity, 1988 Lipooligosaccharides from Treponema hyodysenteriae serotypes 1 through 7, attenuated T. hyodysenteriae serotypes 1 and 2, and five strains of T. innocens were extracted with hot phenol water. The extracts were subjected to sodium dodecyl sulfate-polyacrylamide gel electrophoresis separation and analyzed by lipopolysaccharide selective silver staining ...
