Abstract

This study was performed to determine the seroprevalence of reticuloendotheliosis virus (REV) infection in layer chickens in Gyeonggi province, South Korea. Serum samples were collected from 820 layer chickens on 56 flocks in Gyeonggi province. The samples were tested for specific antibodies against REV using commercial enzyme-linked immunosorbent assay (ELISA). The seroprevalence of REV antibodies in the flocks was 62.50% (95% Confidence interval (CI) 49.33~74.40) and the overall seroprevalence in individual chickens was 39.27% (95% CI 35.97~42.65). The results of the present survey indicate that REV infection is prevalent in layer chickens in Gyeonggi province, South Korea. Therefore, effective measures should be taken to prevent and control REV of layer chickens in this province.
