title: Antigenic differences between strains of Newcastle disease virus.
abstract: Comparison of strains of Newcastle disease virus by kinetic neutralization tests and immunodiffusion tests (after virion disruption by ether and Tween 80) enabled antigenic differences to be demonstrated between four out of five strains tested. No correlation was demonstrated between the antigenic structure and virulence of these strains.
