A female wild raccoon dog was referred with a history of generalized seizure. Mild leukocytosis was noted on laboratory tests. Gross lesions included nasal hemorrhage, hemothorax, and hemorrhage in the urinary bladder with hematuria. Microscopically, interstitial and purulent bacterial pneumonia was observed in the lungs. In the cerebellum, characteristic eosinophilic intracytoplasmic and intranuclear inclusion bodies were found in Purkinje cells, and severe demyelination was observed in the cerebellar white matter. Canine distemper virus (CDV) infection was suspected and confirmed after detection of CDV nucleoprotein RNA in the cerebrum and the lungs by nested reverse transcription polymerase chain reaction (RT-PCR) and reverse transcription loop-mediated isothermal amplification (RT-LAMP). Based on the histopathological and molecular diagnostic findings, it was concluded that the raccoon dog was infected with CDV.

This study was performed to analyze the causative agents of disease occurred in Korean black goat. Bovine viral diarrhea (BVD) and infectious bovine rhinotracheitis (IBR) known as main causative agents of diarrhea and abortion in cattle were founded in Korean black goats. Escherichia coli and Clostridium perfringens are the main causes underlying diarrhea in Korean black goats as well as other animals. In addition, the orf virus was found as a causative agent of contagious ecthyma that shows frequent occurrence in Korean black goats. Leptospirosis was found in Korean black goats with low occurrence rate. However, unlike the reports from many other countries, we could not detect the antibodies for Johne’s disease and Neospora caninum in Korean black goats. These results are likely to contribute to improving the productivity of raising black goats as a field of livestock farming.
