Additional file 5: Figure S5. of Molecular epidemiology and evolutionary histories of human coronavirus OC43 and HKU1 among patients with upper respiratory tract infections in Kuala Lumpur, Malaysia

Phylogenetic analysis of the HCoV-OC43 1a (nsp3) and RdRp gene. Trees were reconstructed using neighbor-joining method. Bootstrap values were calculated from 1,000 trees. Bootstrap values of greater than 70 % were indicated on the branch nodes. The scale bar of individual tree was indicated in substitutions per site, using Kimura 2-parameter model in MEGA (version 5.1) to estimate pair-wise evolutionary distance. (PDF 119 kb)
