Pulmonary venous thrombosis in caprine Pasteurella pneumonia.
A 3-year-old Angora goat that developed acute fibrinous pleuropneumonia associated with Pasteurella haemolytica infection had thrombotic occlusion of a large pulmonary vein. Thrombosis of pulmonary capillaries occurs in pneumonic pasteurellosis, but large vessels are not commonly affected. This unusual lesion may reflect the procoagulant effect of pasteurella endotoxin on vascular endothelium. An incidental observation was the presence of myocardial-type muscle fibres in the tunica media of the pulmonary vein.
