Main Article

Figure 1

Macroscopic and histopathologic features in the red deer in case 1 in study of tuberculosis caused by Mycobacterium microti in red deer, Austria and Germany. A) Gross picture of the cutting surface of the lungs with severe pyogranulomatous pleuropneumonia with multifocal to confluent cavernous granulomas, 2–10 mm diameter. B) Multifocal to coalescing granulomas 4–25 mm diameter on the surface of the epicardium. C) Chronic multifocal to coalescing pyogranulomatous pneumonia in lungs with central areas of necrosis and mineralization surrounded by numerous epithelioid macrophages and a few multinucleated Langhans giant cells. Single lymphocytes and plasma cells were observed around the periphery and between the granulomas, hematoxylin and eosin stain. Scale bar = 20 μm. D) Numerous macrophages and epithelioid cells containing solitary or multiple acid-fast bacilli. Ziehl Neelsen stain. Scale bar = 10 μm.
