A national serological survey of caprine arthritis-encephalitis virus (CAEV) infection was conducted using an enzyme-linked immunosorbent assay (ELISA) and an agar gel immunodiffusion (AGID) test. A total of 658 black goats of various breeds were sampled from 59 farms in three regions of Korea. The CAEV-positive goats were predominantly detected in the Southern region (n=17) as compared with the Northern (n=1) and Central regions (n=0) (χ2=6.26, P=0.044). Among 658 goats tested, 18 were positive in both ELISA and AGID, indicating a CAEV prevalence of 2.73% (95% confidence interval: 1.74–4.28). These results indicate that CAEV is present in Korean black goats.
