  1. High rate of infection with the human T-cell leukemia retrovirus type II in four Indian populations of Argentina.

    Article - En anglais

    Sera from 215 non-drug-injecting Toba and Mataco-Mataguayo pure Indians belonging to four communities in northern Argentina were examined using assays that allow differentiation between reactivities due to type-specific antigens of the human T-cell leukemia/lymphoma virus (HTLV).

    Three of these populations have very little contact with non-Indian groups and reside in remote, isolated areas.

    HTLV-II type-specific seroreactivity was present in 24 (13.7%) of the 175 Indians older than 13 years of age and in none of the 40 who were of younger ages.

    None of the Indians had antibodies reacting with HTLV-I type-specific antigen.

    Seroreactivity was more prevalent and appeared at younger ages in females than in males.
