Genetic analysis of plasmid-encoded mcr-1 resistance in Enterobacteriaceae derived from poultry meat in the Netherlands

Abstract Background Colistin is classified as the highest priority and critically important antimicrobial for human medicine by WHO as it is the last resort agent for treatment of carbapenem-resistant Enterobacteriaceae in humans. Additional research is necessary to elucidate the genetic structure of mcr-1 resistance genes, commonly found on plasmids, using WGS. Objectives To map and compare the genetic characteristics of 35 mcr-1-mediated colistin-resistant Enterobacteriaceae isolated from chicken meat to highlight the genetic variation of the mcr-1-containing plasmids. Methods Sequencing was... Mehr ...
