Abilities of O3L chimeric viruses to mediate low-pH-induced syncytium formation. BS-C-1 cells were infected with viruses at a multiplicity of 2 PFU per cell. After 16 h, cells were treated with a pH 5.5 or pH 7.4 buffer for 2 min. The cells were washed, incubated with fresh medium for an additional 3 h, and then viewed by phase-contrast microscopy.
