This is a case report on the occurrence of caprine arthritis-encephalitis(CAE) disease among dairy goats in a local farm located in Yeongdong-gun, Chungbuk. Previously, it was reported that the farm experienced intermittent deaths numbering 15 of the 97 goats raised for 5 months. Most of the goats less than 6 months of age were suffering from ataxia and posterior paresis, body tremor and abnormal head posterior. Affected animals frequently had stunted growth and had a rough coat. Goats more than 6 months of age were affected with an insidious, chronic arthritis characterized by articular swelling("big knee") of the carpal, hock, and stifle joints. Necropsy revealed severely swollen mesenteric lymph nodes, under-flow of 2-3㎖ synovial fluid in the articular space and fibrous proliferation of synovial membrane. Histopathological examination showed perivascular accumulations of mononuclear inflammatory cells in the white matter of the brain, proliferative synovitis characterized by villous hypertrophy, synovial cell hyperplasia and infiltration by mononuclear inflammatory cells. Pulmonary lesions consists of patchy interstitial pneumonia with hyperplasia of lymphoid tissues and an extensive mononuclear inflammatory cell infiltration into the alveolar septa. Confirmation by nested PCR involves amplification of a 296bp(1st PCR) and 184bp(2nd PCR) fragments corresponding to the gag region of the CAE virus. This is the first time CAE has been reported in a local farm in Korea and emphasizes the importances of developing preventive measures against CAE.

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.
