Fig. 4From: Isolation and characterization of WUPyV in polarized human airway epithelial cellsPhylogenetic tree of WUPyV. The maximum likelihood tree was constructed based on the complete genome sequence of the WUPyV clinical isolate using MEGA 7.0 software. Thirty additional sequences were included as reference strains. Branch points were labeled with bootstrap values, and the strain analyzed in this study was marked with a solid black circleBack to article page
