Figure 1:
Neighbor-joining phylogenetic tree with 1000 bootstrap repeats tests phylogeny method and Tamura 3-parameter model of the nucleotide’s sequences of 620bp IBDV-VP2 gene hypervariable region. The IBDV –VP2 isolates in the study marked as red rhombus.
Figure 2:
Amino acids alignment report of partial sequence of VP2 gene of IBDV and other Egyptian and representative vaccinal strains.
Figure 3:
Neighb.or-joining phylogenetic tree with 1000 bootstrap repeats tests phylogeny method and Tamura 3-parameter model of the nucleotide’s sequences of 420bp IBDV-VP1 gene hypervariable region. The five IBDV –VP1 isolates in the study marked as red rhombus.
