Microbial Biotechnology, Volume 13, Issue 3, Page 669-682, May 2020., 2020 Antibiotic treatment leads to expansion of facultative anaerobic Escherichia spp. (proteobacteria) in calves, a signature of imbalanced microbiota, dysbiosis. This in turn enhances a risk of the growth of bacteria that carry highly mobile clinically relevant resistances that can be transmitted to humans. Summary In agriculture, antibiotics are used for

Emerging Infectious Diseases, 2018 We describe a hospital-based outbreak caused by multidrug-resistant, Klebsiella pneumoniae carbapenemase 3–producing, mcr-1–positive K. pneumoniae sequence type 45 in Portugal. mcr-1 was located in an IncX4 plasmid. Our data highlight the urgent need for

Identification and characterization of mcr mediated colistin resistance in extraintestinal Escherichia coli from poultry and livestock in China [PDF]
, 2017 Antimicrobial resistance to colistin has emerged worldwide threatening the efficacy of one of the last-resort antimicrobials used for the treatment of multidrug-resistant Enterobacteriaceae infection in humans. In this study, we investigated the presence

Regulatory fine-tuning of mcr-1 increases bacterial fitness and stabilises antibiotic resistance in agricultural settings [PDF]
, 2023 Antibiotic resistance tends to carry fitness costs, making it difficult to understand how resistance can be maintained in the absence of continual antibiotic exposure. Here we investigate this problem in the context of mcr-1, a globally disseminated gene

Environment International, 2019 Until recently, the role of insects, and particularly flies, in disseminating antimicrobial resistance (AMR) has been poorly studied. In this study, we screened blowflies (Chrysomya spp.) from different areas near the city of Phitsanulok, Northern ...

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

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