A 2-month-old male Jeju native black calf with respiratory distress was died and requested to the Veterinary Pathology Laboratory of Jeju National University for diagnosis. Grossly, lungs were focally attached to the pleura and heart with fibrin. Purple red sublobar consolidations were distributed in both apical and cardiac lobes of lungs. Histopathologically, diffuse severe bronchointerstitial pneumonia characterized by multifocal necrotizing bronchiolitis, formation of numerous multinucleated syncytial cells in bronchiolar and alveolar lumens, and diffuse alveolar wall thickening were observed in lungs. Eosinophilic intracytoplasmic inclusions were observed in bronchiolar epithelial cells and syncytial cells. According to reverse transcriptase polymerase chain reaction (RT-PCR), bovine respiratory syncytial virus (BRSV) was detected in the lung of calf. Based on the histopathologic findings and RT-PCR, this calf was diagnosed as BRSV infection. In our best knowledge, this is the first case of BRSV infection in Jeju native black calf.
