Phylogenetic analysis of human bocavirus1-4 and other bocavirus members partial
gene sequences. 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, black triangles designate sequences from control group and the others were sequences generated from the gastroenteritis children in the present study. MVC: Minute virus of canines; BPV: Bovine parvovirus.
