Abstract

ABSTRACTWe studied the presence of the mobile colistin resistance genemcr-1in human, animal, and environmentalEnterobacteriaceaesamples from Cumana, Venezuela, that were collected in 2015. Themcr-1gene was detected in 2/93Escherichia coliisolates from swine (novel ST452) and human (ST19) samples that were resistant to colistin. Whole-genome sequencing and transformation experiments identifiedmcr-1on an IncI2 plasmid. One of the isolates also bore the widely spread carbapenemase NDM-1. A One Health approach is necessary to further elucidate the flux of these high-risk genes.
