Phylogenetic analysis and characterization of Korean bovine viral diarrhea viruses
چکیده انگلیسی

Thirty-six bovine viral disease viruses (BVDVs) were identified in bovine feces (n = 16), brains (n = 2), and aborted fetuses (n = 18) in Korea. To reveal the genetic diversity and characteristics of these Korean strains, the sequences of their 5′-untranslated regions (5′-UTRs) were determined and then compared with published reference sequences. Neighbor-joining phylogenetic analysis revealed that most of the Korean viruses were of the BVDV subtypes 1a (n = 17) or 2a (n = 17). The remaining strains were of subtypes 1b (n = 1) and 1n (n = 1). This analysis indicates that the 1a and 2a BVDV subtypes are predominant and widespread in Korea. In addition, the prevalence of BVDV-2 was markedly higher in aborted fetuses than in other samples and was more often associated with reproductive problems and significant mortality in cattle.
