【 摘 要 】

References(24)Cited-By(10)A nationwide survey of bovine leukemia virus (BLV) infection was conducted among dairy and beef breeding cattle in Japan from 2009–2011 using an enzyme-linked immunosorbent assay. Of a total of 20,835 cattle tested, 35.2% were seropositive for BLV and the animal type-level seroprevalences in dairy and beef breeding cattle were 40.9 and 28.7%, respectively. By the time animals were 1 year old, 21.0% of dairy and 13.7% of beef breeding cattle were considered infected. Our findings indicate that BLV is widespread among dairy and beef breeding cattle in Japan with the BLV seroprevalences approximately 10- and 4-fold higher, respectively, than previously reported for 1980–1982 in Japan.
