[Leucocyte migration-inhibition test in syphilis (author's transl)]

The leucocyte migration-inhibition test was performed on blood from 57 patients with syphilis. Even in the early stages of the disease with lymph-node involvement there were signs of cellular antitreponemic reactivity. But there was an absence of cellular immune response in some patients with secondary syphilis and CNS involvement in the course of tertiary syphilis.
