Description:
Bovine, pleural cavity. Large sheets of fibrin cover the costal and diaphragmatic pleura, and form pockets containing straw-colored fluid.

Description:
Bovine, pleural cavity. There is a thick plaque (adhesion) of fibrous tissue on the costal pleura.

Description:
Bovine, lung. Most of the parenchyma is dull, tan, and contains multiple cavities (necrotic); since it is partially surrounded by a fibrous capsule, this necrotic zone is termed a sequestrum. In the viable tissue above and below the sequestrum, the interlobular septa are markedly thickened by fibrous tissue.

Description:
Bovine, lung. Interlobular septa are markedly thickened by fibrous tissue, and also contain small depressions (air pockets = emhysema). Lobules are reddened and wet (congestion and edema).

Description:
Bovine, lung. In the ventral portion of this lung (left side of the image), interlobular septa and the pleura are markedly thickened with fibrous tissue; this pneumonic lung is sharply demarcated from the relatively normal dorsal portion tissue.

Description:
Bovine, lung. The pleura and underlying interlobular septa are severely thickened by fibrous tissue. Lung parenchyma at the lower left is dull and tan (sequestrum).

Description:
Bovine, incised pericardium. The sac is distended with abundant turbid, tan fluid, and abundant fibrin coats the pericardial surfaces.

Description:
Bovine, carpus. The joint capsule and adjacent extensor tendon sheath are markedly thickened and contain excessive fluid. The tendon sheath synovium is congested and covered by small flecks of fibrin.

Description:
Bovine, carpus. There is abundant fibrin within the synovial space and on the synovium, and articular cartilages contain a few small erosions.
