Serological and molecular prevalence of lumpy skin disease virus in Korean water deer, native and dairy cattle in Korea

초록

Lumpy skin disease (LSD) is a severe cross-border infectious disease that causes fever, skin and vis-ceral nodules in cattle. LSD is caused by the lumpy skin disease virus (LSDV), a dsDNA virus that be-longs to the genus Capripoxvirus. Although LSD has been found only in Southern Africa tradition-ally, in the last decade it is spreading very quickly through the Middle East and into Eastern Europe and China. It usually affects cattle and water buffalos being transmitted by blood-feeding insects. As it causes a huge economic impact, LSD is a notifiable disease by World Organisation for Animal Health, and managed as the legal infectious disease class I in Korea. Therefore, the purpose of this study was to confirm the existence of LSDV antigens or antibodies in Korean livestock. We collected 1,200 blood samples from cattle (Korean native and dairy cattle) and Korean water deer in 4 major provinces of the country, then tested the existence of LSDV antigen and antibody. None (0.0%) of the 1,200 blood samples were positive for both antigen and antibody of LSDV. To the best of our knowl-edge, this is the first study that examines the prevalence of LSDV in Korea. Our study aims to report the LSDV occurrence situation obtained by surveillance in Korea and provide information that may help prevention of LSD epidemics.
