"Uncovering the Origins of Syphilis-Like Diseases: Ancient DNA Reveals Surprising Findings"

Researchers in Brazil have discovered the oldest known evidence of a syphilis relative in skeletons dating back 2,000 years, shedding light on the origins of the bacterium Treponema pallidum. The genetic evidence suggests that T. pallidum and T. pallidum endemicum diverged from a common ancestor about 14,000 years ago, challenging the theory that syphilis was brought to Europe by Christopher Columbus. The findings indicate that these bacteria could have traveled around the world with different human migrations much earlier than previously thought.

"Medieval French Skeleton Unveils Surprising Syphilis Discovery"

A medieval French skeleton is challenging the established history of syphilis. Researchers extracted degraded DNA from a femur and identified sequences resembling T. pallidum, the bacterium responsible for syphilis. They also found evidence of an inflammatory immune response, indicating the presence of the disease. However, some experts argue that the organism may be a subspecies related to yaws. The discovery raises questions about the origins and spread of syphilis in Europe, potentially challenging existing historical narratives. It is speculated that Christopher Columbus may have carried a more lethal variant of the disease back to Europe, as he is believed to have suffered from syphilis-like symptoms towards the end of his life.
