Enriched immune T cell suspension protects rabbits against infection with Treponema pallidum
Four groups of rabbits were given intravenously (i.v.) enriched T or B lymphocytes derived from normal or immunized donor rabbits; 24 hrs later, all these animals were infected intradermally (i.d.) with T. pallidum in order to check their immune status. Only rabbits which received immune T cells showed a state of resistance to infection with T. pallidum, whereas recipients of lymphocytes of three other groups did not.
