RESUMO

Peritoneal exudate cells from rabbits infected with Treponema pallidum Nichols were used as indicators of macrophage migration inhibitory factor activity. Between 3 and 15 weeks after infection, the migration of peritoneal exudate cells was inhibited in the presence of 3 to 25 microgram of T. phagedenis biovar Reiter protein per ml. Before this period, the migration patterns of peritoneal exudate cells from infected animals were uninhibited and similar to those from noninfected control rabbits. These observations were correlated with the development of active cell-mediated immunity during experimental T. pallidum infection.
