To characterize the genetic diversity of bovine viral diarrhea viruses (BVDV) circulating in Korea, 11 BVDV isolates were obtained from 467 field samples collected during 2005~2006 in Korea. All of the BVDV isolates were identified as non-cytopathic (non-cp) BVDV biotypes. The 5’ noncoding region (NCR) genes of the isolates were sequenced and analyzed. In total, ten BVDV isolates were typed as BVDV-1 by comparing the genomic sequences to the 5’ NCR. One isolate (05R169) showed 98.6% nucleotide sequence identity with the BVDV-2 reference strain and was therefore typed as BVDV-2. Our results indicate that BVDV-1 is the main genotype circulating in the cattle population of Korea.
