title: Depression of lymphocyte response to concanavalin A in rabbits infected with Treponema pallidum (Nichols strain).
abstract: Peripheral blood lymphocytes isolated from rabbits in the early stages of Treponema pallidum infection responded poorly when exposed to concanavalin A in vitro. Maximal depression of blastogenesis occurred when lymphocytes were cultured in the presence of autologous serum in comparison with fetal calf or normal homologous rabbit serum.
