The authors give the results of a global and rapid study, using a simple methodology, of a suburban onchocerciasis focus located in the vicinity of Brazzaville. It follows, from the entomological, parasitological and clinical data, that the transmission is high inside this focus and therefore, it seems necessary to take, all measures in order to eradicate the focus.

[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.

[Indirect immunofluorescence in the therapeutic surveillance of trypanosomiasis (preliminary note)].

The authors have studied the evolution of fluorescent antibodies in the serum and the C. S. F.
