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

Comparison of Treponema-specific immunoglobulin G (IgG) index with Treponema pallidum particle agglutination (TPPA) index for detection of intrathecal Treponema-specific antibody synthesis for serological diagnosis of neurosyphilis

GMS Infectious Diseases, 2023
The determination of -specific intrathecal immunoglobulin synthesis with the particle agglutination (TPPA) index is a well-established method recommended in German guidelines for the diagnosis of neurosyphilis.

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 ...

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).

Anaerobic Carbon Monoxide Dehydrogenase Diversity in the Homoacetogenic Hindgut Microbial Communities of Lower Termites and the Wood Roach [PDF]

, 2011
Anaerobic carbon monoxide dehydrogenase (CODH) is a key enzyme in the Wood-Ljungdahl (acetyl-CoA) pathway for acetogenesis performed by homoacetogenic bacteria.

Gastric Syphilis Presenting as a Nodal Inflammatory Pseudotumor Mimicking a Neoplasm: Don’t Forget the Treponema! Case Report and Scoping Review of the Literature of the Last 65 Years

Gastroenterology Insights, 2023
Despite the fact that gastric syphilis is considered rare, it is reported as a type of organic involvement that is present in a large proportion of secondary syphilis cases, even though gastritis presenting with symptoms is extremely rare.

The Presence of Treponema spp. in Equine Hoof Canker Biopsies and Skin Samples from Bovine Digital Dermatitis Lesions

Microorganisms, 2021
Equine hoof canker and bovine digital dermatitis are infectious inflammatory diseases of the hooves with an unknown etiology. However, anaerobic spirochetes of the genus Treponema are considered to be potential etiological agents.

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
