Abstract excerpt
Avirulent Newcastle disease viruses (NDV) harbored by waterfowl have the potential to become virulent after transmission to and circulation within chicken populations. In order to investigate how virulent viruses are selected from an avirulent background, we compared the complete sequences of the...
