Abstract

A case of caseous lymphadenitis (CL) was detected in a native Korean goat without manifestation of superficial nodules but with pulmonary abscesses that were characterized microscopically by granulomatous inflammation consisting of a central necrotic region, peripheral fibrous capsule, and numerous cellular infiltrates with epithelioid macrophages, giant cells, and lymphocytes. Presence of Corynebacterium pseudotuberculosis was identified by using bacterial isolation and multiplex PCR. In addition, a 43% seropositivity to C. pseudotuberculosis was observed in goats from the same farm. This case highlights the risk of exposure of farmers to the causative agent and the urgent need for national monitoring for CL, a potential zoonotic.
