Phylogeny and recombination of HPeVs identified in respiratory secretion samples of children. A Phylogenetic tree based on the complete genome of the HPeVs identified in this study and other representative HPeV strains. B Bootscan evidence for the recombination of the HPeV-1 strain xzsgm37 (GenBank no. MW267854). C and D Phylogenetic trees respectively based on upstream and downstream sequences of the putative breakpoint in the recombination analysis. The HPeVs determined in this study are labeled by a red arrow
