Using a radioimmunoassay to detect HTLV-I protein antibodies of molecular weight 24,000, we screened populations from Algeria (140 subjects), Tunisia (442), Mali (69), Senegal (415), Uganda (135), the Central African Republic (77), the Congo (360), and Madagascar (193). Only four subjects were positive (1 from Senegal, 1 from Uganda, 2 from the Congo). This is a much lower figure than that found by others in Africa by the enzyme-linked immunosorbent assay technique. In addition, 319 Portuguese blood donors (46 of whom have lived in Angola or Mozambique) were screened using the same radioimmunoassay. All were negative.

D008875 Middle Aged An adult aged 45 - 64 years. Middle Age
D008970 Molecular Weight The sum of the weight of all the atoms in a molecule. Molecular Weights,Weight, Molecular,Weights, Molecular
D011174 Portugal A country in southwestern Europe, bordering the North Atlantic Ocean, west of Spain. The capital is Lisbon. Madeira Island,Portuguese Republic
D011863 Radioimmunoassay Classic quantitative assay for detection of antigen-antibody reactions using a radioactively labeled substance (radioligand) either directly or indirectly to measure the binding of the unlabeled substance to a specific antibody or other receptor system. Non-immunogenic substances (e.g., haptens) can be measured if coupled to larger carrier proteins (e.g., bovine gamma-globulin or human serum albumin) capable of inducing antibody formation. Radioimmunoassays
D002648 Child A person 6 to 12 years of age. An individual 2 to 5 years old is CHILD, PRESCHOOL. Children
D004797 Enzyme-Linked Immunosorbent Assay An immunoassay utilizing an antibody labeled with an enzyme marker such as horseradish peroxidase. While either the enzyme or the antibody is bound to an immunosorbent substrate, they both retain their biologic activity; the change in enzyme activity as a result of the enzyme-antibody-antigen reaction is proportional to the concentration of the antigen and can be measured spectrophotometrically or with the naked eye. Many variations of the method have been developed.
