Abstract

Bovine viral diarrhea virus (BVDV) is an important worldwide disease in the livestock industry. To characterize BVDV circulating in Gyeongbuk province in the Republic of Korea which has the highest cattle population density, 365 rectal swabs from clinically BVDV Korean indigenous calves were collected. Fifty cases were identified as positive for BVDV. A phylogenetic analysis of 5'- untranslated regions (UTR) revealed that most of our cases belonged to BVDV-2a (n = 48), while only two cases were classified as BVDV-1a (n = 1) and 1b (n = 1), respectively. These results indicated that BVDV-2a is the most prevalent subgroup in Korean indigenous calves of Gyeongbuk province.

소 바이러스성 설사 바이러스는 전세계 축산업에서 중요한 질병이다. 대한민국의 최대 소 사육지역인 경북지방에서 유행하고 있는 소 바이러스 설사 바이러스를 조사하기 위해, 소 바이러스성 설사 바이러스의 임상증상을 보이는 한우 송아지로부터 365개의 분변을 채취하였다. 가검물을 채취한 365 마리 송아지 가운데 50 마리가 소 바이러스성 설사 바이러스에 양성반응을 보였다. 5'-UTR을 이용한 계통발생 분석에서 48두 송아지가 BDVD-2a에 속했고, 2두에서만 각각 BVDV-1a와 BVDV-1b로 분류되었다. 이들 결과는 BVDV-2a가 경북지역의 한우 송아지에서 유행하고 있음을 제시하고 있다.
