Figure 2. Genetic organization of scaffolds (portions of genome sequences reconstructed from end-sequenced whole-genome clones) containing mcr-1 harbored by plasmids pHNSH36, pHNZ319S, and pHNSH138 obtained during analysis of mcr-1–positive Salmonella isolates from pigs at slaughter, China, 2013–2014, and structural comparison with plasmids pHNSHP45–2, pMR0516mcr, and Escherichia coli TN1 contig 18. Arrows indicate positions and direction of transcription of genes. Regions with >99% homology are indicated in gray or blue. Triangles indicate truncated genes. Information in parentheses after isolates indicate source, location, and GenBank accession number.
