Figure. Phylogenetic analysis of nonstructural (NS) 1 gene sequences from human bocavirus 2 strains from Korea (KR), United Kingdom (UK), and Pakistan (PK), presented on a topology tree prepared by using MEGA 3.1 (www.megasoftware.net). Nucleotide alignment of a 417-bp portion of the NS1 gene was prepared by using BioEdit 7.0 (www.mbio.ncsu.edu/BioEdit/BioEdit.html). The nucleotide distance matrix was generated by using the Kimura 2-parameter estimation. Nodal confidence values indicate the results of bootstrap resampling (n = 1,000). Five strains from South Korea (FJ771028–32) are in boldface. Scale bar indicates estimated number of substitutions per 10 bases.
