Abstract
Phylogenetic and nucleotide analysis revealed that severe acute bovine viral diarrhea virus (BVDV) outbreaks from Korean indigenous calves belonged to BVDV-2a, and were identical to those of the highly pathogenic BVDV- 2 strain 890, with identical virulence markers and classified as highly virulent. These outbreaks affected young calves (20 and 40 day-old) and were characterized by hemorrhagic diarrhea, depression, anorexia, and weakness. The identification of the highly virulent BVDV-2 isolates among Korean indigenous calves may have important implications for epidemiological studies, diagnostic and immunization strategies.
