title: Antibody-induced capping of the intracellular stage of Trypanosoma cruzi.
abstract: Intracellular-stage Trypanosoma cruzi were isolated from infected mice. The effect of specific human antibodies on the membrane surface antigens was studied in vitro, using the immunofluorescent technique. The immune serum induced the aggregation of surface antigens, forming polar caps on the amastigotes.
