Fig. 3From: An improved system to generate recombinant canine distemper virusGrowth curve comparison of CDV ZJ and rCDV-ZJ in Vero cells. Cells were infected with parental and recombinant virus at an MOI of 0.01 for 120 h. Viral titers were determined as the number of TCID50/ml in an endpoint titration assay. The data are shown as the mean of triplicates ± SEBack to article page
