a One-step growth curve of PRV-GD2013-ΔgI/gE compared with its parental viruses. Monolayers of BHK-21 cells were inoculated with PRV-GD2013-ΔgI/gE and PRV-GD2013 at 1 MOI. The cell culture supernatants were collected at different time points (0, 4, 8, 12, 16, 20, 24, 28, 32, and 36 hpi), and were used to calculate the TCID50 of each virus. b Plaque morphology and plaque size measurement of PRV-GD2013-ΔgI/gE and PRV-GD2013 on BHK-21 cells at 60 h post-infection. The one-step growth curve and plaque size were measured by one-way repeated measurement analysis variance and least significance (LSD). Differences were considered statistically significant when p < 0.05
