Abstract
|
|
|
|
Multiple enlarged submandibular nodules were discovered during a routine antimortem examination at slaughter in 3 dairy cows of 20-month-old. Grossly, submandibular nodules were firm, reddish, and oval in shape. On cut surface, multiple yellowish abscesses in the parenchyma were observed. Histopathologically, the nodules were characterized by severe diffuse pyogranulomatous inflammation and chronic fibrosis with multiple eosinophilic clubs of Splendore-Hoeppli material containing central bacterial colonies. Trueperella pyogenes was isolated from the lesions. This case was diagnosed as submandibular pyogranuloma caused by Trueperella pyogenes in slaughtered dairy cows in Korea.
