abstract：:Mammalian type C retroviruses can be detected by their induction of foci of cell transformation in S+I - cells. We have noted that certain subtypes of the mouse xenotropic type C retrovirus (MuLV) inhibit this cell alteration. This inhibition, associated with intact virions, is irreversible and gives the infected cell...
