FIG 2.

ML consensus trees (1,000 replicates for bootstrapping) for ORF5 sequences from genotype 1 isolates of Italy. Only bootstrap values of >65% are shown. Panels a and b represent phylogenetic trees resulting from splitting Italian ORF5 sequences into two segments, up to the detected recombination breakpoint (nt 1 to 219) and after the recombination breakpoint (nt 220 to 606). The red strain is the recombinant strain that jumps from the e cluster (green isolates) to the b cluster (blue strains).
