FIG. 6.

Time course of cell-associated virus production in DH 82 cells infected with parental and recombinant viruses. DH 82 cells were infected with a MOI of 0.01, and virus titers were determined by 50% end-point dilution at the indicated times postinfection. The titers represent the average of at least two experiments. Parental viruses were compared with recombinant viruses carrying the same H protein, respectively: MV_Edm [recovered from p(+)MVNSe] with rCDV_OS-H_Edm (A), CDV_OS with rMV-H_OS (B), CDV_OL with rMV-H_OL and rCDV_OS-H_OL (C), and CDV₅₈₀₄ with rMV-H₅₈₀₄ and rCDV_OS-H₅₈₀₄ (D). The respective parental viruses are indicated by solid squares, the recombinant viruses with a MV backbone are indicated by solid triangles, and the recombinant viruses with a CDV backbone are indicated by solid circles.
