Abstract excerpt
Genetic mutations in the genome of infectious bursal disease virus (IBDV) have resulted in antigenic and pathogenic variants that continue to cause disease in commercially reared chickens. The extent of the genetic diversity among IBDV strains circulating in the United States is unknown. This study was designed to identify newly emerging viruses infecting chickens on poultry farms experiencing immune...
