MLST phylogenetic tree of colistin-resistant E. coli isolates obtained from household members. Phylogenetic tree generated using the maximum likelihood method and Tamura-Nei model with a bootstrap test of 1000 replicates using MEGA 11. Values at the nodes represent bootstrap support values. The scale bar represents nucleotide substitutions per site. Shaded isolates possess mcr-1.1 marked with the same single nucleotide mutation. aUnknown
