Bovine Tuberculosis: Elk, lung & lymph node. The lung contains multiple coalescing foci of caseous necrosis surrounded by thin pale fibrous tissue capsules (tubercles). Most of the lymph node is replaced by caseonecrotic debris with a laminated appearance reminiscent of caseous lymphadenitis caused by Corynebacterium pseudotuberculosis.
