Abstract

As a baseline study for the establishment of bovine leukemia virus(BLV)-free herd in Korea, the prevalence of anti-BLV antibody was determined in the present study. Sera from Korean native cows of 8 provinces and from dairy cattle of 9 provinces were subjected to enzyme-linked immunosorbent assay. Anti-BLV antibodies were positive in two (0.14%) of 1,413 Korean native cows. In contrast. 54.2% of 2,415 dairy cows were positive for anti-BLV antibodies, and their seropositive herd rate was 86.8%. And no differences were found in the sero-positive rates with age. The results indicate that the BLV infection rate has been increased continuously in Korea and that the establishment of BLV-free herd is imminent.
