Molecular typing of Treponema pallidum: a 5-year surveillance in Shanghai, China.
Previously, a small study showed that 14f was the predominant subtype of Treponema pallidum in Shanghai, China. The result was quite different from the genotype distribution in other areas of China. This study aimed to identify the strain types of Treponema pallidum in samples collected over a 5-year period in Shanghai. From 2007 to 2011, genital swabs were collected from patients with syphilis...
متن کاملMolecular typing of treponema pallidum clinical strains from Lisbon, Portugal.
A molecular system was used to subtype Portuguese Treponema pallidum clinical strains isolated from both skin lesions and blood. The study with this system constitutes the first typing study in a European country. Three T. pallidum subtypes were found: subtypes 14a (50%), 14d (45.2%), and 14f (4.8%). Further studies are needed to better characterize the isolates involved in syphilis outbreaks.
متن کاملEnhanced molecular typing of treponema pallidum: geographical distribution of strain types and association with neurosyphilis.
BACKGROUND Strain typing is a tool for determining the diversity and epidemiology of infections. METHODS Treponema pallidum DNA was isolated from 158 patients with syphilis from the United States, China, Ireland, and Madagascar and from 15 T. pallidum isolates. Six typing targets were assessed: (1) the number of 60‐bp repeats in the acidic repeat protein gene, (2) restriction fragment length ...
متن کاملMolecular Typing of Treponema pallidum: A Systematic Review and Meta-Analysis
BACKGROUND Syphilis is resurgent in many regions of the world. Molecular typing is a robust tool for investigating strain diversity and epidemiology. This study aimed to review original research on molecular typing of Treponema pallidum (T. pallidum) with three objectives: (1) to determine specimen types most suitable for molecular typing; (2) to determine T. pallidum subtype distribution acros...
متن کاملMolecular Studies in Treponema pallidum Evolution: Toward Clarity?
Syphilis is the best known treponemal infection and the disease has captured the attention of well-known physicians and the imaginations of writers and artists. In contrast, the nonvenereal treponemal infections (yaws, bejel, and pinta) have been endemic in remote regions of Africa, Southeast Asia, and South America, and are thus less well-known in western culture. However, these endemic trepon...
