Abstract

The prevalence of bovine viral diarrhea virus (BVDV) in Korean indigenous calves with diarrhea in Gyeongbuk province was investigated. Seventy-five cases were identified as BVDV positive in the diarrhea stools. Phylogenetic analysis revealed that all our cases were classified as BVDV-2a. Most of the present BVDV-2a cases were isolated from calves showing clinical signs of watery diarrhea. Our observations indicate that not all BVDV-2 infections cause clinically severe disease. This study shows the high incidence of BVDV-2 infection in Gyeongbuk province. Therefore, the results suggest that a vaccine development and immunization strategies are required for the effective control of BVDV infection in the Republic of Korea.

경북지역에서 설사증상을 보이는 한우송아지를 대상으로 소 바이러스성 설사 바이러스의 유병률이 조사되었다. 75두의 송아지가 소 바이러스성 설사 바이러스에 양성 반응을 나타내는 것으로 확인되었다. 계통발생 분석시 양성반응을 보이는 75두 송아지가 BVDV-2a로 분류되었다. BVDV-2a로 분류된 대부분은 수양성 설사의 임상증상을 나타내는 송아지로부터 채취한 것이었다. 우리의 결과에 따르면 모든 BVDV-2 감염이 심각한 임상증상을 보이지 않는 것으로 나타났다. 이 연구는 경북지역에서 BVDV-2 감염의 높은 발생률을 보여준 것으로, 이 연구 결과는 백신개발 및 예방 전략이 대한민국에서 BVDV 감염의 효과적인 근절을 위해 필요한 것으로 사료된다.
