[Post-therapeutic evolution of patients presenting an immunological suspicion of trypanosomiasis without parasitological proof in support of it (author's transl)].

The authors have recently preconised systematic treatment of every human being who is fluorescent positive. The evolution of antibodies of 26 subjects parasitologically negative and positive only in FAT test is described here after treatment with Arsobal. Statistically the antibodies decrease progressively like antibodies of Sleeping Sickness patients of first period usually did. Therefore it is possible to conclude that immunological suspects who were treated were realy sick and rightly cured.
