Figure 1. Sequence comparison of scaffolds (portions of genome sequences reconstructed from end-sequenced whole-genome clones) identified in mcr-1–positive plasmids pHNSH36, pHNZ319S, and pHNSH138 with 2 mcr-1–bearing plasmids pHNSHP45-2 (GenBank accession no. KU341381) and pMR0516mcr (GenBank accession no. KX276657), and contigs identified in mcr-1–positive genomes of Escherichia coli strain NT1 in BRIG (11) (GenBank accession LSBW01000090.1) obtained during analysis of mcr-1–positive Salmonella isolates from pigs at slaughter, China, 2013–2014. Arrows indicate positions and direction of transcription of genes. Reference plasmids pHNSHP45–2 (A) and pMR0516mcr (B) are indicated in black in the outer circles.
