[Comparative immunoelectrophoretic analysis of culture and bloodstream forms of "trypanosoma" (Trypanozoon) brucei gambiense". Demonstration of stage and antigenic type specific antigens (author's transl)].

The comparative immunoelectrophoretic analysis of the antigenic structures of culture and bloodstream forms with cross absorption tests confirm the existence among Trypanosoma gambiense antigens of: --numerous antigenic components common to culture and bloodstream forms;--several antigenic components specific of either culture forms or bloodstream forms. Among the latter, two components are shown to be specific of the antigenic type and appear to support the immunochemical specificity of each variant.
