one was related to severe local ischemic necrosis, one had a large nodular grey lesion on an 

 auricula, and one was active but non-erupted. 



Multi-focal circulations with evidence of dermzil involvement were spread over the 

 entire body of one animal, one other animal had numerous light grey irregular spots on its 

 ventral abdomen and a third animal had white circular punctate scars distributed over its 

 body as well as a few healed parallel scars (probably healed con-specific tooth-rake marks). 



An endometrial cyst and a Monorygma cyst were observed in one animal (the possible 

 mastitis diagnosis), and a tan mass was observed on the ovary of another animal. 



Serosanguinous fluid was found in the abdominal cavity of one animal and in the 

 thoracic and peritoneal cavities of another. 



A full-term fetus was found in two animals. One of these animals was the possible 

 calving-associated mortality and the other was a non-indicated mortality. 



Adhesions were observed between the limg to the thoracic wall, and in the intestinal 

 loops to each other, to the pseudopancreas and to the mesentery, in one animal, and 

 between the intestinal loops and the liver and diaphragm (preventing diaphragmal reflection) 

 in another. 



Mild to severe fibrosis was observed in the lungs, liver, lymph nodes, pancreas and 

 pseudopancreas of six animals. Lymphoid atrophy was noted in one animal, and hyperplasia 

 and lymphoid depletion were found in three animals. 



The following bacterial isolates were reported: enterics, Salmonella and gram-negative 

 bacilli from skin samples; enterics, Clostridium, gram-negative bacilli, Pseudomonas and 

 Aeromonas from lungs; enterics and Aeromonas from intestines; gram-negative bacilli and 

 ciliated protozoans from the spleen; and an acute E.coli infection in a lymph node 

 (suggesting immunocompromise). 



No viral isolates were found. 



Worn teeth (moderate to extreme), indicating an older animal, were observed in five 

 animals. Minimal teeth wear was observed in two animals, one of which had immature 

 testes, all indicating a younger animal.
