Figure 2.

ML phylogenetic tree of the pVP2 sequence of IPNV (1536 bp). The Italian IPNV strains are shown in bold. Reference strains sequences are shown in grey. The genogroup subdivision (I-VII) according to Blake et al. (2001) and Nishizawa et al. (2005) is reported. Monophyletic clusters containing Italian strains and arbitrarily named A, B, C and D are highlighted with grey boxes. The putative reassortant strain, IPNV/S.trutta/I/UD/406/Jun90, is labeled with two asterisks (**). The numbers at nodes represent bootstrap values (only values ≥ 70% are reported). Branch lengths are scaled according to the number of nucleotide substitutions per site. The tree is mid-point rooted for clarity only.
