syphilis

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.
