The plasmid-mediated colistin resistance gene, mcr-1, was detected in an Escherichia coli
isolate from a Danish patient with bloodstream infection and in five E. coli isolates from …

We identified a novel plasmid-mediated colistin-resistance gene in porcine and bovine
colistin-resistant Escherichia coli that did not contain mcr-1. The gene, termed mcr-2, a 1,617 …

A novel variant of the plasmid-borne colistin resistance gene mcr-3 was detected on an
IncHI2 plasmid in an ST131 CTX-M-55-producing Escherichia coli isolate from a Danish …

Recently, the plasmid-mediated colistin resistance gene mcr-1 was found in
Enterobacteriaceae from humans, pigs and retail meat in China. Several reports have …

On 18 November 2015, Liu et al. reported the first description of plasmid-mediated colistin
resistance (mcr-1 gene) in food animals, food and humans in China [1]. In this issue …

This report describes one Salmonella isolate harbouring both mcr-1 and mcr-3. We also
found nine other Salmonella isolates positive for the plasmid-borne colistin resistance gene …

We report a high prevalence of MCR-1 and CTX-M-1-producing Escherichia coli in three
Tunisian chicken farms. Chickens were imported from France or derived from French …

A novel mcr colistin resistance gene was identified in a strain of Salmonella enterica,
monophasic variant of serovar Typhimurium (4, 5, 12: i:-), isolated from a pig at slaughter in …

Colistin resistance genes mcr-3 and mcr-1 have been detected in an Escherichia coli isolate
from cattle faeces in a Spanish slaughterhouse in 2015. The sequences of both genes …

Background and aim Plasmid-mediated colistin resistance mechanisms have been
identified worldwide in the past years. A multiplex polymerase chain reaction (PCR) protocol …
