Contagious Bovine Pleuropneumonia: 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.

Contagious Bovine Pleuropneumonia: 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).

Contagious Bovine Pleuropneumonia: 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.
