FIG.3.

Phylogenetic analysis of hMPV isolates. The sequences of nucleotides 688 to 1032 of the F gene were determined. The corresponding gene sequences of previously reported Canadian and Dutch hMPV isolates were also included. Phylogenetic analysis was performed by the neighbor-joining method of the MEGA program. The previous Canadian isolates are indicated by CAN followed by the year of collection and the isolate number (e.g., CAN97-83). The isolates presented in this study are indicated by the isolate number and the year (e.g., 172-02). The Dutch isolate is indicated by NDL00-1.
