Figure 2. Phylogenetic analyses of sequences from the complete Nipah virus P ORF (A), M ORF (B), F ORF (C), G ORF (D), and L ORF (E). Tree created with maximum parsimony, close-neighbor-interchange algorithm, 1,000 bootstrap replicates (16). Branch lengths are in units of number of changes over the whole sequence. Available GenBank accession numbers are shown for corresponding sequences. Proposed genotype groupings are indicated by brackets (M, B). ORF, open reading frame; MY, Malaysia; KH, Cambodia; BD, Bangladesh; IN, India; HU, human; PI, pig; BA, bat. Scale bars indicate number of sequence changes corresponding to illustrated branch length.
