Fig. 2From: A molecular epidemiological investigation of contagious caprine pleuropneumonia in goats and captive Arabian sand gazelle (Gazella marica) in OmanRepresentative graphs of gross, histopathological and IHC examinations of the necropsied CCPP naturally infected goats; A Peracute form represented by lung congestion, severe pulmonary edema and white-colored foamy fluid in the trachea; B Acute form showing marbling appearance and hepatization of the lungs, hydrothorax, and fibrinous pleuritis C Chronic form characterized by unilateral pleural adhesion (arrowhead), lung hepatization and severe hydrothorax; D Photomicrograph of pulmonary tissue showing fibrin threads deposition in a bronchiole (arrowhead) and surrounding alveoli besides obliteration of another bronchiole with inflammatory cells (asterisk) (H&E, bar=200µm); E Consecutive section of (D) stained with anti-Mccp antibody showing intense brown positive staining in the fibrin deposits, inflammatory cells obliterating the bronchioles and alveoli, and the peribronchial lymphoid aggregates (DAB staining, Hematoxylin counterstaining, bar=200µm)Back to article page
