Figure 6. . Immunohistochemical detection of avian infectious bronchitis virus (IBV) antigens in tissues after experimental infection with IBV YN strain. Panels A, C, E, and G correspond to control tissues. B) Tracheal tissue with viral antigen detected extensively in the epithelial cells of the tracheal mucosa (black arrow). Scale bar = 50 μm. D) Lung tissue with viral antigen detected in alveolar cells (black arrow). Scale bar = 50 μm. F) Kidney tissue with viral antigens detected widely in the renal tubular epithelial cells (black arrow). Scale bar = 50 μm. H) Bursa tissue with viral antigens detected at high levels in mucosal epithelium in the bursa of Fabricius (black arrow). Scale bar = 100 μm.
