Non-infectious, non-neoplastic
This condition is seen in aborted and stillborn animals that fail to breath after birth
What is atelectasis?
This route of infection is common for bacterial agents associated with bronchopneumonia.
What is aerogenous/air-borne?
This is the site of injury for interstitial pneumonia.
What is alveolar and/or interlobular septa?
This pattern of distribution can frequently be used to describe embolic pneumonia.
What is multifocal to coalescing?
This condition of suppurative exudate filling the pleural cavity can result in dogs with migrating grass awns.
What is pyothorax?
This finding occurs with obstructive disease resulting in hyperinflation of alveoli.
What is emphysema?
This histologic finding is associated with chronic damage to the airways, forming a luminal polyp of fibrous tissue.
What is bronchiolitis obliterans?
This cell type proliferates following damage to alveolar epithelial cells.
What are type II pneumocytes?
This is a primary malignant pulmonary neoplasm arising from the alveolar epithelium.
What is broncho-alveolar carcinoma?
In chronic inflammatory conditions of the pleura, this gross finding may be seen, contributing to restrictive disease.
What are pleural fibrotic adhesions?
This finding is frequently seen as a sequalae to congestive heart failure.
What is hydrostatic edema?
These lung lobes are most affected by aspiration of foreign material, such as rumen content.
What are cranial and middle lung lobes?
This factor can predispose cattle to developing an atypical interstitial pneumonia due to toxic metabolites which form in the rumen.
What is lush pasture rich in L-tryptophan?
These nodules can sometimes be differentiated from abscesses by increased firmness grossly and large numbers of epithelioid macrophages found histologically.
What are granulomas?
This condition results from seeding of the pleural space by a pulmonary carcinoma, appearing grossly similar to mesothelioma.
What is carcinomatosis?
Endocrinopathies, such as Cushing's disease can predispose dogs to pulmonary thromboembolism through this mechanism, which is part of Virchow's triad.
What is hypercoagulability?
This predisposing factor is specifically linked to the development of disease with Mannheimia haemolytica in cattle.
What is exposure to cold?
This histologic finding is indicative of viral infection with a tropism for type II pneumocytes and alveolar macrophages.
What are multinucleated giant cells?
In addition to a granulomatous pneumonia, these tissues are frequently affected by blastomycosis in dogs.
What are brain, bone, eyes, lymph nodes, and skin?
This bacterial genus is commonly associated with polyserositis, particularly in pigs.
What is Streptococcus sp.?
Hemosiderin-laden alveolar macrophages are frequently seen on histologic section of lungs from animals in left-sided heart failure due to this mechanism.
What is pulmonary venous hypertension?
This clinical finding is frequently seen in animals with bronchopneumonia due to a reduction in vital capacity.
What is hypoxemia?
This is the mechanism by which interstitial pneumonia is refractory to supplemental oxygen.
What is barrier to gas diffusion?
This lung condition in ruminants can result from subacute ruminal acidosis where there is breakdown of the mucosal barrier.
What is fungal embolic pneumonia?
This intestinal disease can result in decreased oncotic pressure, leading to pulmonary edema and hydrothorax.
What is protein-losing enteropathy?
