[Diagnostic value of parasitologic examinations and of indirect immunofluorescence test in S. haematobium schistosomiasis (author's transl)].

A study has been carried out in 690 patients admitted in a Paris hospital and from Mali, Senegal and Mauretania origin, in order to compare the three available techniques for the diagnosis of infection with S. haematobium: urine centrifugation deposit control, biopsy of rectal mucosa and indirect immunofluorescence test. The prognostic value of each of these three techniques has been reevaluated. (Formula: see text), Living eggs have been detected in 55 p. 100 of the patients by direct examinations and a prevalence of 75 p. 100 has been computaned for S. haematobium.
