The deduced amino acid sequences of segment A and B of two very virulent Infectious bursal disease virus (vvIBDV) isolates, UPM94/273 and UPM97/61 were compared with 25 other IBDV strains. Twenty amino acid residues (8 in VP1, 5 in VP2, 2 in VP3, 4 in VP4, 1 in VP5) that were common to vvIBDV strains were detected. However, UPM94/273 is an exceptional vvIBDV with usual amino acid substitutions. The differences in the divergence of segment A and B indicated that the vvIBDV strains may have been derived from genetic reassortment of a single ancestral virus or both segments have different ability to undergo genetic variation due to their different functional constraints.
