Interpretive Summary:

Technical Abstract: Increased mortality, lymphoma and decreased egg production were observed in a turkey breeding flock for over 20 weeks. Reticuloendotheliosis virus (REV) infection was confirmed by virus isolation and serology. Progeny poults from these breeders were seropositive for REV at hatch, but performance of these flocks was normal and neoplasia was not observed. One month after the breeding flock was diagnosed with REV, a few meat turkey flocks from the same integrator experienced increased condemnation due to lymphoma in a few organs. The pox vaccine used in breeders tested negative for contamination with REV. The origin of REV in these breeders could not be determined.
