 AB    With the goal of establishing an in vitro system of dual infection with
       human T cell lymphotropic viruses (HTLV) types I and II, rabbit
       lymphocytes were cocultured with a mixture of lethally irradiated
       HTLV-I-producing Ra-1 and HTLV-II-producing RII cell lines. This gave
       rise to a lymphoid cell line, RW-1, that was dually infected with HTLV-I
       and -II as detected by immunofluorescence staining, electron microscopy,
       and polymerase chain reaction using primers specific for the pol and env
       regions of each virus and by Southern blot hybridization. Two clonal
       cell lines derived from RW-1 were also coinfected with the viruses,
       indicating that dual infection had occurred at the single cell level.
       The coinfection could be readily propagated to fresh lymphocytes by
       coculture with RW-1. In contrast, attempts to superinfect
       HTLV-I-infected lymphoid cell lines with HTLV-II and vice versa were
       consistently unsuccessful, suggesting receptor interference between
       HTLV-I and -II.
