Phylogenetic analysis of the partial
gene sequences of human bocavirus1-4 and other bocavirus members. Phylogenetic tree was constructed by the neighbor-joining method, Kimura 2-parameter model with 1,000 bootstrap replicates, by using MEGA 4.1 package. Black dots designate reference strains, the others were sequences generated from the present study. MVC: Minute virus of canines; BPV: Bovine parvovirus.
