Distribution of Jembrana disease in cattle in Indonesia.

An enzyme-linked immunosorbent assay (ELISA) was used to detect antibodies to Jembrana disease virus in sera of cattle in Indonesia. Antibodies were detected in cattle from Bali island and some districts of Lampung (Sumatra), West Sumatra and East Java provinces but not in other areas of Indonesia. Clinical Jembrana disease or Jembrana-like diseases have been reported to occur in Bali cattle (Bos javanicus) in all four areas where antibody was detected and not in the other areas where antibody was not detected. The results indicate there has been only limited spread of Jembrana disease from endemic areas to adjacent areas.
