Endemic treponematoses- Countries with reported data on yaws, bejel, and pinta from 1980 to 2012[1]
SpecialtyInfectious disease

Treponematosis is a term used to individually describe any of the diseases caused by four members of the bacterial genus Treponema. The four diseases are collectively referred to as treponematoses:[2]

  • Syphilis (Treponema pallidum pallidum)
  • Yaws (Treponema pallidum pertenue)
  • Bejel (Treponema pallidum endemicum)
  • Pinta (Treponema carateum)

Traditional laboratory tests cannot distinguish the treponematoses.[3] However, sequence differences among the T. pallidum subspecies have been identified. Molecular approaches involving PCR to identify these sequences are being developed.[1]
