Altered baby hamster kidney (BHK-R) cells were serially cultured in the continuous presence of hemagglutinating virus of, Japan (HVJ). These cells showed a distinct resistance to superinfection with the homologous HVJ. This resistance of BHK-R cells gradually disappeared after serial passages in the presence of ultraviolet-irradiated HVJ particles which lost infectivity but still preserved hemagglutinating and neuraminidase activities. When BHK-R cells were serially cultured in the presence of a temperature-sensitive mutant of HVJ at non-permissive temperature, the cells also lost the resistance. The resistance of BHK-R cells remained unchanged, even after prolonged incubation in virus-free maintenance medium under the conditions of no cell division. It was suggested that killing of virus-sensitive cells, which were generated during cell proliferation, was required for maintenance of the resistance.
