[Monoclonal integration of simian T-cell leukemia virus in hamadryas with malignant lymphoma]. / Monoklonal'naia integratsiia virusa T-kletochnogo leikoza obez'ian u pavianov gamadrilov so zlokachestvennoi limfomoi.

The association of simian T-cell leukemia virus with baboons malignant lymphoma was studied. Proviral DNA integrated in cells of lymphoid organs was detected in 19 of 21 sick animals examined. Only 4 of 10 monkeys from high risk colony without clinical manifestations had virus-specific sequences in their cellular DNAs. As a rule, S(H)TLV-I-infected cells monoclonally proliferated both in lymphomatous and healthy baboons. The restriction patterns with EcoRI, HindIII, PstI, BamHI of S(H)TLV-I provirus were similar but not identical to those of prototype HTLV-I and STLV-I isolates.
