FIG. 4.

WT and CA074^R rVSV-GPΔMuc viruses grow equally well in Vero cells. WT or CA074^R rVSV-GPΔMuc were adsorbed to confluent monolayers of Vero cells at an MOI of 3 FFU/cell at 4°C. Following removal of the viral inoculum, the cells were washed with culture medium and shifted to 37°C. At the indicated times, an aliquot was taken from the supernatant, and viral titers were determined by FFA. Averages ± standard deviations for four trials from a representative experiment are shown.
