a Histopathological examination of the trachea from chicken in group I showing desquamation of tracheal epithelium (notched arrow) and collection of tissue debris and fibrinous material infiltrated with inflammatory cells in the tracheal lumen (star) × 4. b The examined trachea of chickens of group II showing deciliation with desquamation of tracheal epithelium (arrow), bar = 50. c The examined trachea of chickens of group III showing hyperplasia of the epithelial layer cells infiltrated with inflammatory cells in the trachea (star) and oedema into the lamina propria (notched arrow), bar = 50. d In the trachea, obtained from (group IV) showing deciliation with proliferation of undifferentiated epithelium infiltrated with inflammatory cells (star), bar = 100. e In the higher magnification, infiltration of epithelium with inflammatory cells (star) accompanied with haemorrhage and infiltration of inflammatory cells in the lamina propria (arrow), bar = 50.(H&E)
