Phylogenetic tree of the complete genomes of 27 representative human (black) and camel (red) MERS-CoV strains rooted by NeoCoV (KC869678.4). Phylogenetic tree of the complete genomes of 27 representative human (black) and camel (red) MERS-CoV strains rooted by NeoCoV (KC869678.4). The tree was constructed by the neighbor-joining method using MEGA 5.0. The scale bar indicates the estimated number of substitutions per 2,000 nucleotides. Jasper F. W. Chan et al. Clin. Microbiol.
