Abstract Objectives In November 2015, a plasmid-mediated colistin resistance, MCR-1, was
described in animals, food and humans in China, and it was considered as a potential …

Since the first description of a plasmid-mediated colistin resistance gene (mcr-1) in
November 2015 multiple reports of mcr-1 positive isolates indicate a worldwide spread of …

The emergence of the plasmid-mediated colistin resistance gene mcr-1 is threatening the
last-line role of colistin in human medicine. With mcr-1-positive Escherichia coli (E. coli) …

Purpose To investigate the increasing prevalence of colistin resistance in animal
Escherichia coli isolates and their mcr-1-carrying plasmids, especially those shared by …

We hereby report the first characterization of mcr-3 gene from healthy animals in South
Korea. Out of 636 E. coli isolates, collected between 2014-2017, nine colistin resistant …

Objectives In response to the first report of transmissible colistin resistance mediated by the
mcr-1 gene in Escherichia coli and Klebsiella spp. from animals and humans in China, we …

Colistin is used to treat infectious diseases in humans and livestock; it has also been used
as a feed additive for livestock for approximately 50 years. Since the mcr-1 plasmid …

Background: The emerging mobile colistin resistance gene, mcr-1, is an ongoing worldwide
concern and an evaluation of clinical isolates harboring this gene is required in Korea. We …

Objectives This study investigated the prevalence and characteristics of mcr-1-harbouring
Escherichia coli isolated from chickens in central China from 2014 to 2019. Methods A total …

Antimicrobial resistance to colistin has emerged worldwide threatening the efficacy of one of
the last-resort antimicrobials used for the treatment of multidrug-resistant Enterobacteriacea …
