Figure 2
Growth curves (one-step growth kinetics) of rMDV-HA, MDV 814 and rHVT-HA.
After inoculation of chickens with 100 PFU of each virus, virus titers were determined at different times and steadily increased from 48 to 96 h post-infection until maximal titers were reached. The data of the growth curve of rHVT-HA were cited from reference [18]. Stars indicate that the differences were significant between the groups (P<0.05).
