title: Genetic relatedness of virulent and avirulent strains of Marek's disease virus.
abstract: Comparative studies using Southern blot hybridization indicated that the avirulent strains of Marek's disease virus (MDV) were probably generated through DNA rearrangement that occurred in the limited area(s) of the virulent MDV genome.
