The results presented demonstrate that outbreaks of virulent Newcastle disease in Australia arose from the emergence of virulent virus from an endemic avirulent quasispecies. Environmental selection pressures, or industrial practices, led to the emergence of this species and its dominance in several distinct ourbreaks from 1998-2002.
