In vivo pathogenicity of IBV and rIBV-wt. Tracheal ciliostasis scores per individual animal and means per experimental group are plotted. Maximal ciliostasis score per animal is 40, which indicates complete ciliostasis in all 10 transversal tracheal sections examined. Ciliostasis as determined at 7 days p.i. with vaccine strain IBV H52 BI, rIBV-wt or non-vaccinated (5 animals per group)
