Rhee, Y.O. | Heo, Y. | Kim, Y.H. | Sul, D.S. (Rural Development Administration, Anyang (Korea R.). Veterinary Research Inst.)
The prevalence of antibody to Getah virus was serologically followed among those horses in Korea. Blood samples were taken from 575 horses in Feb and 462 horses in Sep. 1985. Overall percentage of horses with seropositive to Getah virus was 37% in Feb and 47% in Sep. The data suggest that the Getah virus infection was endemic in Korea and the increase in prevalence may be associated with the seasonal activity of arthropod vectors. This entails preventive precautions of the horses against this viral infection before the entry into Korea

Park, N.C. | Choi, W.P. (Kyongbuk National Univ., Taegu (Korea R.))
This paper described the distribution and transmissibility of BLV (bovine leukemia virus), the relationship between antibodies against BLV and lymphocyte count in 313 dairy cattle from 36 herds, the clinical signs and hematological findings of 2 lymphosarcomatous cattle in the northern area of Kyongbuk. Eighty three (26.5%) of 313 cattle from 36 herds were positive for BLV antibodies and 19 (52.8%) of 36 herds were infected with BLV by the immunodiffusion test with BLV-gp antigen. The rate of BLV infection in cattle varied from 9.5 to 87.5% in 19 positive herds, it was higher in herds pastured during summer and included lymphosarcomatous onset than the other and also higher with the age
