Newcastle disease (ND) is a viral disease of poultry affecting domestic and wild avian species and humans (Al-Garib et al., 2003). Newcastle Disease is of great economic importance, causing devastating losses, with mortality as high as 100% seen in some cases among both intensive, extensive and traditional village poultry production systems across the developing world (Anon, 2010; Wernery et al., 1992).
