Presence of antibodies to human lymphoma-leukemia virus (HTLV-I) in Germans with symptoms of the acquired immunodeficiency syndrome (AIDS).

Sera from German patients exhibiting symptoms compatible with the acquired immune deficiency syndrome (AIDS) or the lymphadenopathy syndrome (LAS) were assayed for antibodies against human T-cell lymphoma/leukemia virus (HTLV-I)-related antigens by enzyme immunoassay, indirect immunofluorescence, and radioimmunoprecipitation. Antibodies against HTLV were detected in 3 out of 31 sera.
