The staining pattern of MPT64-positive cells in tuberculosis cases as detected by immunohistochemistry. (a) MPT64 expressed in a tuberculous lymphadenitis case from Norway. Antigen was mainly seen in the epithelioid and giant cells and not in the necrotic centers (NC). The surrounding lymph node tissue was negative. (b) The marked area in (a) shown at higher magnification. (c) A representative area from the granuloma showing a multinucleated giant cell with strong staining for MPT64.
