1. Spleen: Dermatitis, necroulcerative, acute, focal ly 



extensive, moderate, with numerous mixed gram-negative bacilli 



and ciliated protozoa, Atlantic bottlenose dolphin ( Tursiops 



truncatus), cetacean. 



n Liver: Hepatitis, portal to periportal, lymphoplasmacytic 



and eosinophilic, diffuse, mild to moderate. 



3. Liver: Congestion, centri lobular, diffuse, moderate. 



4. Liver: Extramedullary hematopoiesis, multifocal, mild. 



5. Lung, pleura: Fibrosis, focal ly extensive, moderate, with 

 fibrous adhesions. 



6. Lung: Congestion and alveolar edema, diffuse, moderate, 

 with alveolar histiocytosis. 



7. Lymph node: Lymphoid depletion, diffuse, moderate. 



8. Lymph node: Lymphadenitis, eosinophilic, diffuse, mild. 



9. Lymph node: Congestion, diffuse, moderate, with mild 

 hemorrhage. 



Comment: The skin lesion is suggestive of cutaneous infarction. The presence of 

 bacteria deep within the lesion raises the possibility that the lesion was caused 

 by septic thromboembolism. However, bacterial invasion through the skin is also 

 possible. Ciliated protozoa are found rather commonly in skin lesions of this 

 type in dolphins. They are generally considered to be secondary invaders. The 

 hepatic and pulmonary congestion are probably agonal. The pleural fibrosis and 

 adhesions are probably the result of a resolved pneumonia and pleuritis. The 

 causes of the other lesions are not apparent.
