FIG 8.
Infectivities of pseudotyped VSVs in mammalian cell lines. VSVΔG*-Zaire, VSVΔG*-Reston, VSVΔG*-Lloviu, VSVΔG*-Angola, and VSVΔG*-Musoke were inoculated into several mammalian cell lines. (A) Infectious units (IUs) of each virus in different cell lines were determined by counting the number of GFP-expressing cells, and each IU value was standardized based on 106 copies of the VSV genome as determined by real-time RT-PCR. (B) Relative infectivities in bat cell lines are given by setting each IU value in Vero E6 cells to 1.0 (i.e., [IU in bat cells]/[IU in Vero E6 cells]). Each experiment was performed three times, and averages and standard deviations are shown. Infectivities of VSVΔG*-Angola and VSVΔG*-Musoke were under the limit of detection (*).
