Growth kinetics of the recombinant viruses rZM10 and rZM10-RFP. DF-1 cells were infected with the indicated NDV viruses at 0.01 MOI. Every 12Â h post-infection, virus lysates were harvested. Virus titers were measured by TCID50 titration on DF-1 cells for each time point in triplicates from two independent experiments and expressed in mean log10 TCID50/mL with a deviation
