Whole genome sequence of the Treponema pallidum subsp. endemicum strain Iraq B: A subpopulation of bejel treponemes contains full-length tprF and tprG genes similar to those present in T. p. subsp. pertenue strains

PLoS ONE, 2020
Treponema pallidum subsp. endemicum (TEN) is the causative agent of endemic syphilis (bejel). Until now, only a single TEN strain, Bosnia A, has been completely sequenced.

In Vitro Cultivation of the Syphilis Spirochete Treponema pallidum

Current Protocols, Volume 1, Issue 2, February 2021., 2021
Abstract 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 organism in co‐culture with mammalian tissue culture cells.

The pan-genome of Treponema pallidum reveals differences in genome plasticity between subspecies related to venereal and non-venereal syphilis

BMC Genomics, 2020
Background Spirochetal organisms of the Treponema genus are responsible for causing Treponematoses. Pathogenic treponemes is a Gram-negative, motile, spirochete pathogen that causes syphilis in human. Treponema pallidum subsp.

Treponema pallidum infection in the wild baboons of East Africa: distribution and genetic characterization of the strains responsible. [PDF]

PLoS ONE, 2012
It has been known for decades that wild baboons are naturally infected with Treponema pallidum, the bacterium that causes the diseases syphilis (subsp. pallidum), yaws (subsp. pertenue), and bejel (subsp. endemicum) in humans.

Surveying bovine digital dermatitis and non‐healing bovine foot lesions for the presence of Fusobacterium necrophorum, Porphyromonas endodontalis and Treponema pallidum

Veterinary Record, Volume 186, Issue 14, Page 450-450, April 2020., 2020
Background Non‐healing bovine foot lesions, including non‐healing white line disease, non‐healing sole ulcer and toe necrosis, are an increasingly important cause of chronic lameness that are poorly responsive to treatment. Recent studies have demonstrated a high‐level association between these non‐healing lesions and the Treponema phylogroups ...
