A new study suggests syphilis may have been circulating in Europe before Columbus returned from the Americas, Science reports.

That Gene There

Genetic diversity in one gene appears to help the bacterium that causes syphilis evade the immune system.

From infant skeletal remains going back hundreds of years, a team produced three Treponema pallidum genomes, representing both syphilis- and yaws-causing sub-species.

The test is designed to detect and differentiate herpes simplex virus types 1 and 2, Treponema pallidum, and varicella-zoster virus.

Researchers sequenced dozens of Treponema pallidum isolates associated with syphilis, yaws, or bejel to look at the emergence of pandemic syphilis.

The firm said that the system is unique because it consists of cell, immunoassay, and nucleic acid tests within one platform.
