Colistin-phage combinations decrease antibiotic resistance in Acinetobacter baumannii via changes in envelope architecture

open access: yes, 2021
Multidrug-resistant bacterial infections are becoming increasingly common, with only few last-resort antibiotics such as colistin available for clinical therapy.

MCR-1 Confers Cross-Resistance to Bacitracin, a Widely Used In-Feed Antibiotic

open access: yesmSphere, 2018
Extensive use of colistin in food animals is deemed a major driving force for the emergence and transmission of mcr-1. However, a non-colistin usage factor(s) contributing to mobile colistin resistance may also exist in animal production systems.

Evidence of international transmission of mobile colistin resistant monophasic Salmonella Typhimurium ST34

open access: yesScientific Reports, 2023
AbstractS. 4,[5],12:i:-, a monophasic variant of S. enterica serovar Typhimurium, is an important multidrug resistant serovar. Strains of colistin-resistant S. 4,[5],12:i:- have been reported in several countries with patients occasionally had recent histories of travels to Southeast Asia. In the study herein, we investigated the genomes of S. 4,[5],12:

Evolutionary drivers of mobile colistin resistance

open access: yes, 2022
Antibiotics are our strongest defence against disease causing bacteria. This makes the threat of widespread antibiotic resistance all the more concerning. Last-resort antibiotics such as colistin are especially important as they are effective against multiple-drug resistant pathogens.

Mobile Plasmid Mediated Transition From Colistin-Sensitive to Resistant Phenotype in Klebsiella pneumoniae [PDF]

open access: yesFrontiers in Microbiology, 2021
Multidrug-resistant bacteria, including carbapenem-resistant Klebsiella pneumoniae (CRKP), are becoming an increasing health crisis worldwide. For CRKP, colistin is regarded as “the last treatment option.” In this study, we isolated a clinical CRKP strain named as K. pneumoniae R10-341.

Colistin: A mainstay antibiotic for treatment of fatal Gram negative bacterial infections [PDF]

open access: yesERU Research Journal
Our world is facing an enormous disaster due to spreading of the life-threatening bacterial infections, especially after the spread of multidrug-resistant Gram-negative bacteria (MDR-GNB), including those resistant to known antibiotics such as ...

Comprehensive Genomic Investigation of Coevolution of mcr genes in Escherichia coli Strains via Nanopore Sequencing

open access: yesGlobal Challenges, 2021
Horizontal gene transfer facilitates the spread of antibiotic resistance genes, which constitutes a global challenge. However, the evolutionary trajectory of the mobile colistin resistome in bacteria is largely unknown. To investigate the coevolution and

Prevalence and molecular epidemiology of mcr-mediated colistin-resistance Escherichia coli from healthy poultry in France after national plan to reduce exposure to colistin in farm

open access: yesFrontiers in Microbiology, 2023
IntroductionWithin the 2007–2014 programme for the surveillance of antimicrobial resistance (AMR) in livestock in France, mcr-1 prevalence average in commensal Escherichia coli was found to be 5.9% in turkeys and 1.8% in broilers, indicating that mobile ...

Pre-existing chromosomal polymorphisms in pathogenic E. coli potentiate the evolution of resistance to a last-resort antibiotic

open access: yeseLife, 2022
Bacterial pathogens show high levels of chromosomal genetic diversity, but the influence of this diversity on the evolution of antibiotic resistance by plasmid acquisition remains unclear. Here, we address this problem in the context of colistin, a ‘last

Silent spread of mobile colistin resistance gene mcr-9.1 on IncHI2 ‘superplasmids’ in clinical carbapenem-resistant Enterobacterales [PDF]

open access: yesClinical Microbiology and Infection, 2021
mcr-9.1 is a newly described mobile colistin resistance gene. We have noted its presence in multiple species of carbapenem-resistant Enterobacterales (CRE) from our institution. We aimed to determine the clinical features, genomic context and phenotypic impact of mcr-9.1 carriage in a series of patients between 2010 and 2019.We identified 32 patients ...
