a The examined bursae from chickens in group II showing hyperplasia of the follicular epithelium (arrow) associated with mononuclear infiltration in subepithelial connective tissue (star), bar = 50. b The examined bursae in chickens of group III showing enlarged and tightly packed lymphoid follicles with cortical and medullary lymphocytes (star) with enfolded follicular reticuloepithelial layer (arrow), bar = 50. c In the bursae, obtained from group IV showing proliferation of the inter-follicular stroma infiltrated with inflammatory cells (star) and epithelial cysts in the hyperplastic epithelium (notched arrow), bar = 100. d Interstitial haemorrhage (arrow), bar = 50. e The epithelized cysts observed in few follicles (arrow), bar = 100. f Formation of pyogranuloma (notched arrow) with necrotic center (star), bar = 100.
