Treponema
Treponema is a genus of spiral-shaped bacteria. The major treponeme species of human pathogens is Treponema pallidum, whose subspecies are responsible for diseases such as syphilis, bejel, and yaws. Treponema carateum is the cause of pinta.[2] Treponema paraluiscuniculi is associated with syphilis in rabbits.[3] Treponema succinifaciens has been found in the gut microbiome of traditional rural human populations.[4]
