Abstract

We tested serum specimens from patients with HAM/TSP and asymptomatic HTLV-I carriers from endemic areas of Japan, Jamaica, Colombia, and Chile for neutralizing antibodies against HTLV-I. The data suggest a trend for neutralizing activity to be found more frequently in the sera from HAM/TSP patients than in sera from asymptomatic carriers. The result of this study emphasizes the importance of determining biologic properties of the envelope glycoprotein of HTLV-I.
