[Macrophage migration inhibition test in untreated syphilis].

Two modifications of macrophage migration inhibition test, one of George and Vaughan and the other one of Svejcar, were performed on a total of 78 cases of untreated syphilis at various stages. As specific antigens were used: Treponema Pallidum ultrasonate and cardiolipin. Inhibition of migration was observed in 87 percent patients with primary syphillis and in all patients with late and late congenital syphilis. After improving and standardisation of the technique of Treponema Pallidum antigen-the migration inhibition test may be recommended as a specific in vitro-test for detection of cell mediated immunity in syphilis.
