title: [Induction, by 5-bromo-2'-deoxyuridine, of a "foamy" virus previously undetected in hamster cells transformed by SV40].
abstract: TSV5 clone 2 cells in normal conditions of culture contain only an expressed RNA virus (R-type virus). However, exposure of the cells to 5-bromo-2'-deoxyuridine with dexamethasone, induced synthesis of a syncitium-forming ("Foamy") virus. In other hamster cell lines, the same treatment fails to induce a "foamy" virus. The origin of this "foamy" virus is discussed.
