FA4-EGFP induced higher robust neutralizing activity than the inactivated vaccine. SPF chickens randomly divided into 5 groups were immunized with inactivated vaccine or infected with different doses of the recombinant virus FA4-EGFP. The neutralizing activity (NT) of sera from the inoculated chickens were tested at 7 dpi (A), 14 dpi (B) and 21 dpi (C), and then these chickens were challenged with the lethal dose of FAdV-4 at 21 dpi. D Percent of survival for the challenged chickens.
