Bovine tuberculosis: Florid, granulomatous lymphadenitis in a buffalo (wtbflor3)
Almost all the normal tissue from this lymph node has been replaced by a tan-coloured granulomatous inflammatory reaction. Note the absence of a capsule around the granuloma, and the lack of any form of necrosis. In these type of lesions, few, if any, acid-fast bacteria are seen in histological sections of the tissue, or in tissue smears made for diagnostic purposes.
