Protection based criteria were: virus re-isolation attempts from trachea, tracheal and renal histopathology as well as IBV antigens detection by immunofluorescent antibody technique in kidney sections. In the present study, Egypt/F/03 was isolated from 25day-old broiler chickens in Fayoum Governorate, identified by Dot-ELISA, RT-PCR and sequenced to determine its serotype. In this study, an Egyptian IBV strain; Egypt\F/03 was isolated from a tissue pool of kidney and trachea from unvaccinated broiler flock with a history of respiratory and renal disease. Challenge experiments to evaluate cross-protection induced at the trachea and kidney level by vaccine strains and Belgian nephropathogenic isolates of avian infectious bronchitis virus	./cache/cord-276550-1in7m56w.txt	./txt/cord-276550-1in7m56w.txt
