영문 초록

Ruminant pestiviruses of bovine viral diarrhea virus (BVDV) and border disease virus (BDV) are closely related to classical swine fever virus (CSFV) and all belong to the genus of Pestiviruses. BVDV is one of the most important viral pathogen of cattle and has been recorded in most countries where cattle are raised. Natural host for BVDV is cattle, but BVDV is able to infect pigs as well. The purpose of this study was to investigate the prevalence for antibodies against BVDV in domestic pig farms in South Korea from 2009 to 2011. In this study, 2,755 pigs in 239 farms in South Korea s inland and 5,293 pigs in 613 farms in Jeju province (CSF free region) were investigated for antibodies against two pestiviruses, BVDV and CSFV by a virus neutralization test (VNT). The seroprevalences on the individual level and on herd level against BVDV were 5.3 % and 21.2 % in South Korea s inland, 5.2 % and 6.5 % in Jeju province, respectively. Based on the ratio of respective antibody titers by the comparative VNT, 273 pigs in Jeju province with BVDV infection were detected and they were distinctly negative to CSF. It is recognized that porcine infections with BVDV naturally occurred in Jeju province. Whereas, antibody titers against BVDV of South Korea s inland were cross-reactivity with CSFV.
