NDM-5-Producing Escherichia coli Co-Harboring mcr-1 Gene in Companion Animals in China

open access: yesAnimals, 2022
Carbapenem and colistin are important antibiotics for the treatment of infections caused by multidrug-resistant Gram-negative pathogens. Here, we isolated the blaNDM-5-harboring Escherichia coli in companion animals in healthy or diseased companion ...

Expanding landscapes of the diversified mcr-1-bearing plasmid reservoirs [PDF]

open access: yes, 2017
BACKGROUND: Polymyxin is a cationic polypeptide antibiotic that can disrupt bacterial cell membrane by interacting with its lipopolysaccharide molecules and is used as a last resort drug against lethal infections by the carbapenem-resistant superbugs ...

Genomic Features of MCR-1 and Extended-Spectrum β-Lactamase-Producing Enterobacterales from Retail Raw Chicken in Egypt. [PDF]

open access: yes, 2021
Colistin is considered as a last resort agent for treatment of severe infections caused by carbapenem-resistant Enterobacterales (CRE). Recently, plasmid-mediated colistin resistance genes (mcr type) have been reported, mainly corresponding to mcr-1 ...

Occurrence and spread of carbapenemase‐producing Enterobacterales (CPE) in the food chain in the EU/EFTA. Part 1: 2025 update

open access: yesEFSA Journal, Volume 23, Issue 4, April 2025.
Abstract Carbapenemase‐producing Enterobacterales (CPE) have been reported in the food chain in 14 out of 30 EU/EFTA countries. Commonly reported genes are blaVIM‐1, blaOXA‐48 and blaOXA‐181, followed by blaNDM‐5 and blaIMI‐1. Escherichia coli, target of most of the studies, Enterobacter cloacae complex, Klebsiella pneumoniae complex and Salmonella ...

Genomic Characterization of Two Escherichia fergusonii Isolates Harboring mcr-1 Gene From Farm Environment

open access: yesFrontiers in Cellular and Infection Microbiology, 2022
The prevalence and transmission of mobile colistin resistance (mcr) genes have led to a severe threat to humans and animals. Escherichia fergusonii is an emerging pathogen which is closely related to a variety of diseases.

DNA Polymerase IV dinB Favors the Adaptive Fitness of mcr‐carrying Bacteria Through a Negative Feedback Regulatory Mechanism

open access: yesAdvanced Science, Volume 12, Issue 12, March 27, 2025.
This work demonstrates that DNA polymerase IV dinB favors the adaptive fitness of mcr‐carrying bacteria via a negative feedback regulatory mechanism. Specifically, the elevation of ROS production by intact mcr activates dinB, which in turn represses the mcr expression, maintaining a balance between colistin resistance and bacterial fitness.

Mutational change of CTX‐M‐15 to CTX‐M‐127 resulting in mecillinam resistant Escherichia coli during pivmecillinam treatment of a patient

open access: yesMicrobiologyOpen, Volume 8, Issue 12, December 2019., 2019
In this study, we investigated the genetics behind mecillinam resistance which occurred in an extended‐spectrum β‐lactamase‐producing Escherichia coli during pivmecillinam treatment of a patient. The genomic comparison of the two isolates points toward a mutational change of blaCTX‐M‐15 into blaCTX‐M‐127 along with a serotype shift from rough to full ...

Rapid Increase in the IS26-Mediated cfr Gene in E. coli Isolates with IncP and IncX4 Plasmids and Co-Existing cfr and mcr-1 Genes in a Swine Farm

open access: yesPathogens, 2021
This paper aimed to investigate the molecular epidemiological features of the cfr gene in E. coli isolates in a typical swine farm during 2014–2017. A total of 617 E. coli isolates were screened for the cfr gene using PCR amplification.

Integrated Genomic and Phenotypic Characterization of an Mcr-10.1‐Harboring Multidrug Resistant Escherichia coli Strain From Migratory Birds in China

open access: yesTransboundary and Emerging Diseases, Volume 2025, Issue 1, 2025.
Background: The global rise in antibiotic resistance among multidrug resistant (MDR) Gram‐negative (GN) bacteria has posed significant health challenges, leading to the resurgence of colistin as a key defense against these bacteria. However, the widespread use of colistin has resulted in the rapid emergence of colistin resistance on a global scale. Ten
