Characterization of DKR/FSS chimeric viruses in cell culture. Comparison of replication kinetics of DKR, FSS, CH-I, and CH-II in Vero (A), BHK-21 (B), C6/36 (C) and U4.4 (D) cells. All cells were infected at a MOI of 0.01. Viral titres were measured at indicated time points using plaque assays on Vero cells. Means and SDs from six independent replicates (indicated by dots) are shown. L.O.D., limitation of detection (100 PFU/ml). Two-way analysis of variance (ANOVA) was performed to analyze the statistical differences between the titres of DKR, FSS, CH-I, and CH-II at the indicated time points. *, P < 0.05 (significant); **, P < 0.01 (very significant); ****, P 0.0001 (extremely significant).
