Figure 4From: Construction of a full-length infectious bacterial artificial chromosome clone of duck enteritis virus vaccine strainPlaque area measurement of DEV-vac, rDEV, rDEV-BAC, and rDEV-Cre on CEFs. The means and standard deviations of sizes of 100 plaques of each virus were measured with Image J software. The mean of the plaque area of DEV-vac was set at 100%. Standard deviations are shown with the error bars.Back to article page
