Abstract excerpt
Newcastle disease virus (NDV) causes an economically important disease that can vary from clinically inapparent to highly virulent forms. Generally, NDV strains isolated from wild birds are non-pathogenic for chicken. However, there are evidences supporting the fact that avirulent viruses maintained in feral birds could have caused outbreaks of virulent NDV in poultry. The strain-specific difference in virulence...
