title: Natural antibodies to simian type-C viruses and human retrovirus HTLV in patients with lymphoid malignancies.
abstract: Blood plasma samples from adult patients and children with malignant lymphoproliferative diseases were studied for presence of antibodies to primate type-C viruses by membrane immunofluorescence. Antibodies to baboon endogenous virus could be detected in various types of lymphoid leukaemias and lymphomas. Gibbon ape leukaemia virus-specific antibodies were mainly found in B- and O-cell leukaemias and lymphomas. Anti-HTLV antibodies could be detected only in a few cases of T-cell malignancy. There was no evidence of a horizontal transmission of such viruses.
