The serological status of unvaccinated turkey birds to infectious bursal disease virus (IBDV) antibody on a livestock farm in Abeokuta was determined using the Enzyme Linked Immunosorbent Assay (ELISA) technique. A total of 51 turkeys were sampled and the result indicated the presence of IBDV antibody in 37 (72.5%) birds. Since turkeys may serve as carriers of chicken serotype 1 virus, it is recommended that the virus eliciting antibody in the birds be isolated and characterized.Key words: IBDV antibody, unvaccinated turkeys, ELIS
