Technical Abstract: Recently, several avian orthoreoviruses have been isolated from commercial turkeys affected by Poult Enteritis Complex (PEC), a disease syndrome with uncertain etiology. Molecular characterization has shown that these turkey-origin reoviruses (TRVs) are unique among avian orthoreoviruses. The effect of a particularly pathogenic TRV strain on poult cell-mediated and humoral immunity was evaluated using a phytohemaglutanin toe-web inflammation assay and by measuring antibody response to Newcastle Disease Virus vaccine, respectively. The results of these assays suggest that TRV infection can lead to poult immune-dysfunction and may predispose poults to subsequent infections associated with the PEC disease state.
