Abstract
Purified axial filaments from the cultivable Reiter treponeme, previously shown to share an antigenic component with pathogenic Treponemia pallidum, were evaluated as antigen in a diagnostic test for syphilis. Antibody to the filaments was revealed by counterimmunoelectrophoresis. Conditions that produced optimal results in the test were established. A total of 343 sera from normal individuals, biological false-positive reactors, and from patients in the different stages of syphilis were subjected to the test. The results indicate the test to be sensitive and highly specific for detecting treponemal antibodies in human syphilis.
