Prevalence of natural infection of chickens with reticuloendotheliosis virus (REV) was explored using egg yolk extract as the source of antibody in the indirect immunofluorescence reaction. One-hundred forty-seven of 905 eggs from 41 of 92 chicken flocks in 12 states contained the antibody. Although there was considerable geographic variation consistent with sampling problems, it is apparent that this is a common virus infection of North American chickens. Results of the cross-immunofluorescence test confirmed that REV is not a member of the well-characterized sarcoma-leukosis group of avian viruses. |
