From: Molecular detection of colistin resistance genes (mcr-1 to mcr-5) in human vaginal swabs
Phylogenetic tree of sequences in five mcr genes. The nucleotide sequences of colistin resistance genes (mcr-1, 342 bp; mcr-2, 282 bp; mcr-3, 267 bp; mcr-4, 1062 bp; mcr-5, 197 bp) in human beings obtained this study (in bold font) were compared with those of representative mcr variants obtained from NCBI. The sequences from animals in Yangzhou, the same city for human samples, are shown with red font. The evolutionary history was inferred using the Neighbor-Joining method. The tree is drawn to scale, with branch lengths in the same units as those of the evolutionary distances used to infer the phylogenetic tree
