Abstract

A survey was performed on the outbreak of listeriosis in a Korean native goat in Animal Breeding Station of Gyeongsang National University, Chinju, Korea. Clinical signs in the affected goat were fever, dullness, inappetence, nasal discharge, slobbering, dysphagia, circling, incoordination, recumbency, unilateral facial paralysis, torticollis, dyspnea, spasmodic paddling movement of the limbs and death at 6 days after onset. No significant gross lesions were seen. The histopathological lesions were consisted of perivascular edema and cuffs by round cells and microabscess with infiltration of neutrophils, lymphocytes and macrophages in the cerebrum. Gram-positive organism was observed in the microabscess lesions. Listeria monocytogenes was isolated exclusively from the brain tissue by cultural examination and the lesions induced by experimental infection with the isolate were characterized by severe conjunctivitis in rabbit and hepatic necrotic foci in mouse. This seems to be the first report of listeriosis in Korean native goat.
