Abstract
The complete genome sequence of a Chinese very virulent infectious bursal disease virus (vvIBDV) strain, Harbin-1, was determined. Based on the sequence analysis, the molecular characteristics and potential virulence determinants and origin of vvIBDV strains were identified. Phylogenetic analysis indicated that a reassortment and/or recombination event may have occurred in the emergence of Chinese vvIBDV strains.
