Rescue of Very Virulent and Mosaic Infectious Bursal Disease Virus from Cloned cDNA: VP2 Is Not the Sole Determinant of the Very Virulent Phenotype
1 Aug 2000
Abstract excerpt
Many recent outbreaks of infectious bursal disease in commercial chicken flocks worldwide are due to the spread of very virulent strains of infectious bursal disease virus (vvIBDV). The molecular determinants for the enhanced virulence of vvIBDV compared to classical IBDV are unknown. The lack of a reverse genetics system to rescue vvIBDV from its cloned cDNA hampers the identification and study of these...
