The evaluation of protection conferred by live vaccines against the virulent IS/885 and IS/1494 isolates was assessed based on ciliary activity in the tracheal explants prepared from vaccinated-challenged chicks (Darbyshire 1980 , Andrade and others 1982 , Marquardt and others 1982 , Snyder and others 1983 , Cook and others 1999 and gross lesions in the trachea and kidneys following the challenge with the respective viruses. 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-001768-8vljd5cv.txt	./txt/cord-001768-8vljd5cv.txt
