First was a German field isolate (Virus A) passaged in Vero cells [9] and found avirulent in turkeys [12] , second was Virus AvF which contained an F gene modification found to better induce protection in turkeys [12] and third was 309/04, a virulent field isolate deriving from a subtype A vaccine and arising in field conditions [23] . When IBV MF recombinants were used to inoculate one-day-old chickens, many induced IBV protection of the trachea, yet serology and real time RT PCR virus detection indicated poor tracheal replication. Induction of protective immunity in chickens vaccinated with infectious bronchitis virus S1 glycoprotein expressed by a recombinant baculovirus	./cache/cord-260667-5aurua6o.txt	./txt/cord-260667-5aurua6o.txt
