Any change of mucin secretion in larynx, trachea and bronchi, and in trachea with mucoid plugs/casts of ILTV infected chickens was studied. MUC5AC and MUC5B were present only in the dorsal tracheal region of the cranial and middle-tracheal mucosa of control chickens. The tracheal lumen diameter was almost 40% less in ILTV infected chickens due to mucosa thickening. MUC5AC and MUC5B were scarcely observed in larynx, trachea and bronchi, and in trachea with plugs/casts of ILTV infected chickens. Reduced tracheal lumen diameter and DNA fibrous structures connected with nuclei of cells in trachea with plugs/casts were observed in ILTV infected chickens.
