Abstract
Multi-drug resistance poses a serious threat to the public health worldwide. The situation becomes worse when multidrug-resistant bacteria develop resistance against last resort antibiotics such as colistin attributed to plasmid-borne mcr genes. Humans and non-human animals including pigs and chickens are the main reservoirs of these mcr genes harboring bacteria which have now disseminated globally, thus, causing difficulties in treating bacterial infections. Several mcr-gene-containing bacterial (MGCB) species have been found in diverse ecosystems, including aquatic, soil, botanical, wildlife, animal, and public environments. Environmental samples have shown to contain the mcr-1, mcr-2, mcr-3, mcr-5, mcr-7, and mcr-8 genes variants. The genes are found in Escherichia coli, Enterobacter, Klebsiella, Proteus, Salmonella, Citrobacter, Pseudomonas, Acinetobacter, Kluyvera, Aeromonas, Providencia, and Raulotella isolates. The routes of transmission of MGCB are contact with reservoirs that contain mcr, consumption of contaminated animal-/plant-based foods or water, trade and travel that involve animal-/plant-based foods. An updated and precise estimation of prevelance as well as mechanism of colistin resistance mediated by mcr genes is inevitable to regulate the spread of colistin resistance by implementing effective strategies. Hence, this review presents a comprehensive overview of epidemiology and the various mechanisms of colistin resistance that are currently not clearly understood.
期刊介绍:
Applied Biochemistry and Microbiology is an international peer reviewed journal that publishes original articles on biochemistry and microbiology that have or may have practical applications. The studies include: enzymes and mechanisms of enzymatic reactions, biosynthesis of low and high molecular physiologically active compounds; the studies of their structure and properties; biogenesis and pathways of their regulation; metabolism of producers of biologically active compounds, biocatalysis in organic synthesis, applied genetics of microorganisms, applied enzymology; protein and metabolic engineering, biochemical bases of phytoimmunity, applied aspects of biochemical and immunochemical analysis; biodegradation of xenobiotics; biosensors; biomedical research (without clinical studies). Along with experimental works, the journal publishes descriptions of novel research techniques and reviews on selected topics.
