Phylogenetic analysis of hMPV isolates. The putative ORFs for N, P, M, F, M2-1, M2-2, SH, and G were analyzed. The corresponding gene sequences from APVC were also analyzed. Bootstrap proportions were plotted at the main internal branches of the phylogram to show support values. Note that the scale of each tree was different. Phylogenetic analysis was performed by use of the neighbor-joining method of the MEGA program.
