Syphilis is usually sexually transmitted but may also pass from an infected pregnant woman to her unborn child (congenital syphilis). The last of three stages of syphilis is the most severe and can cause damage to the heart, blood vessels, brain and spinal cord.

About the Artist - Biomedical Imaging Unit, Southampton General Hospital
Science Photo Library was founded in 1981 by Michael Marten, one of the authors of "Worlds Within Worlds", a book exploring different ways to observe the universe - from electron micrographs, to images of earthrise taken from the Apollo spacecraft. When Marten started receiving requests for the beautiful images in the book, he had an idea of setting up Science Photo Library.
Since then, Science Photo Library has continued to work alongside world acclaimed photographers and the leading science and medical experts to provide a central source of the best science and specialist imagery available. Although the collection started with scientific images, it has grown to encompass all aspects of science and their impact on everyday life.
