[Value of Cricetomys gambianus in the study of experimental trypanosomiasis from Trypanosoma gambiense. Methods for mass preparation of antigen and purification of serum exoantigen].

Methods for mass preparation of crude antigen and exoantigen of Trypanosoma gambiense from experimentally infected Cricetomys gambianus are described. The size of this animal and the hyperparasitism obtained make it a remarkable source of trypanosomian antigens.
