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.
