Phosphoprotein Contributes to the Thermostability of Newcastle Disease Virus

Figure 4

Thermostability of parental viruses (rNDV4C and rLaSo) and chimeric viruses (rNDV4CLaSoP and rLaSoNDV4CP). Heat-inactivation kinetics of HA activity (a) and virus titer (b) of the indicated recovery NDVs were determined at 56°C. P < 0.05 and P < 0.005 are presented as and , respectively.
