Case Report: A Case of Caprine Arthritis Encephalitis in Dairy Goat Farms in South Korea.

One Saanen dairy goat () farm in Korea reported that some goats showed clinical signs such as arthritis, paralysis, carpal joint swelling, and even death. We monitored clinical signs and pathological lesions. In the laboratory, we confirmed caprine arthritis encephalitis virus (CAEV) infection by polymerase chain reaction (PCR). We examined all the dairy goats on the farm and found that many of them were positive. In conclusion, CAEV infection was detected in the majority of the goats in this farm, and it induced severe clinical signs impacting productivity and causing important economic shortfalls. We need to regularly investigate all dairy goat farms, and, more importantly, inspection of the quarantine stage should be required before importation. Interestingly, we found all negative results in Korean native black goats ().
