Overview
Yaws is a tropical infection of the skin, bones and joints caused by the spirochete bacterium Treponema pertenue. Other treponematosis diseases are bejel (Treponema endemicum), pinta (Treponema carateum), syphilis (Treponema pallidum), and Lyme Disease (Borrelia burgdorferi).
Causes
Yaws is an infection caused by the spiral-shaped bacteria, Treponema pallidum, subspecies pertenue. It is closely related to the bacterium that causes syphilis, but this disease is not sexually transmitted.
Diagnosis
Laboratory Findings
A sample from a skin sore is examined under a special type of microscope called darkfield examination. There is no blood test for yaws. However, the blood test for syphilis is usually positive in people with yaws because the bacteria that cause these two conditions are closely related.
