Yaws: 110 Years After Castellani's Discovery of Treponema pallidum subspecies pertenue [PDF]

, 2015
Yaws is a neglected infectious disease that affects mostly children and adolescents living in poor, rural communities in humid, tropical areas of Africa, southeast Asia, and the Pacific Islands.

Diagnostics for Yaws Eradication: Insights From Direct Next-Generation Sequencing of Cutaneous Strains of Treponema pallidum. [PDF]

, 2017
BACKGROUND: Yaws-like chronic ulcers can be caused by Treponema pallidum subspecies pertenue, Haemophilus ducreyi, or other, still-undefined bacteria. To permit accurate evaluation of yaws elimination efforts, programmatic use of molecular diagnostics is

Molecular Diagnosis of Syphilis in Brazilian Ambulatory Patients: Detection of <i>Treponema pallidum</i> subsp. <i>pallidum</i> in Serum Using Ancient DNA Protocols. [PDF]

Microorganisms
The rising incidence of syphilis in recent decades underscores the need to improve diagnostic and control strategies. The infection caused by Treponema pallidum subsp. pallidum is commonly diagnosed using serological tests. However, these methods exhibit

Primates in Burrows: A Cause for Concern? Observations From a One Health Perspective at Niokolo Koba National Park, Senegal

Ecology and Evolution, Volume 15, Issue 4, April 2025.
Burrows are places where many species cross paths and potentially exchange diseases. Primates are not known to frequent burrows. However, in the Niokolo Koba National Park (Senegal) primates entering in burrows and come potentially into contact with other species, including bats.

Outcome Predictors in Treatment of Yaws

Emerging Infectious Diseases, 2011
To estimate failure rates after treatment with benzathine penicillin and to identify determinants of failure that affected outcomes for yaws, we conducted a cohort study of 138 patients; treatment failed in 24 (17.4%).

Two Streptococcus pyogenes emm types and several anaerobic bacterial species are associated with idiopathic cutaneous ulcers in children after community-based mass treatment with azithromycin.

PLoS Neglected Tropical Diseases, 2022
BackgroundIn yaws-endemic areas, two-thirds of exudative cutaneous ulcers (CU) are associated with Treponema pallidum subsp. pertenue (TP) and Haemophilus ducreyi (HD); one-third are classified as idiopathic ulcers (IU).

Coinfection of a yaws patient with two closely related Treponema pallidum subsp. pertenue strains : A rare event with potential evolutionary implications [PDF]

The etiological agent of yaws is the spirochete Treponema pallidum (TP) subsp. pertenue (TPE) and infects the children of Papua New Guinea, causing ulcerative skin lesions that impairs normal growth and development.

Genetic diversity in Treponema pallidum: Implications for pathogenesis, evolution and molecular diagnostics of syphilis and yaws [PDF]

, 2012
Pathogenic uncultivable treponemes, similar to syphilis-causing Treponema pallidum subspecies pallidum, include T. pallidum ssp. pertenue, T. pallidum ssp. endemicum and Treponema carateum, which cause yaws, bejel and pinta, respectively.
