Image_1_Characterization of Escherichia coli Carrying mcr-1-Plasmids Recovered From Food Animals From Argentina.TIF

<p>In this study, we found mcr-1.1 and mcr-1.5 genes carried by IncI2 plasmids in a subset of Escherichia coli isolates recovered from commercial broiler farms in Argentina. The comparative analysis of the sequences of these plasmids with those described in human clinical isolates suggests that this replicon-type is one of the main mcr-disseminator sources in Argentina.</p

Comparison of pMCRs described in this study.

<p>Arrows indicate the following predicted open reading frames: conjugation, stability, and accessory genes (green, yellow), antimicrobial resistance genes (<i>mcr-1</i> in red; <i>mcr-1</i>.<i>5</i> in dark red), transposon-related genes (blue), hypothetical proteins (grey), shufflon segments (black), and replicase genes (brown). The light blue-shaded areas show regions with ~100% identity among the compared structures; grey-shaded areas, 50% identity or lower.</p

Sequence alignment of IncI2-type <i>mcr-1</i>-bearing plasmids.

<p>pHNSHP45 was used as a reference to compare with the pMCRs described here and with other IncI2 plasmids. The outer circle with red arrows indicates annotation of the reference sequence. Gaps in the inner circles are missing regions when compared with the reference.
