Molecular epidemiology of mcr gene group [PDF]

Клиническая микробиология и антимикробная химиотерапия, 2020
Colistin and polymyxin B are the “last reserve” antimicrobials for the treatment of extensively drug-resistant Gram-negative bacterial infections. The rapidly increasing prevalence of polymyxin resistance mediated by the mcr gene localized on plasmid DNA

Antimicrobial Activity of a Polymyxin A-like Compound and Characterisation of the Cognate Biosynthetic Gene Cluster Within the Genome of the Producing Paenibacillus polymyxa [PDF]

Antibiotics
Background: Here, we report the isolation and identification of a Paenibacillus polymyxa strain from the citizen science project, Swab and Send. P. polymyxa is well known for its production of polymyxin E (colistin), and polymyxin B.

Emergence of high-level colistin resistance mediated by multiple determinants, including mcr-1.1, mcr-8.2 and crrB mutations, combined with tigecycline resistance in an ST656 Klebsiella pneumoniae

Frontiers in Cellular and Infection Microbiology, 2023
Colistin and tigecycline are usually regarded as the last resort for multidrug-resistant Klebsiella pneumoniae infection treatment. Emergence of colistin and tigecycline resistance poses a global healthcare challenge and is associated with high mortality

Fusion plasmid carrying the colistin resistance gene mcr of Escherichia coli isolated from healthy residents

Journal of Global Antimicrobial Resistance, 2022
: Objectives: The extensive spread of colistin resistance represents an enormous concern to infectious disease treatment, because colistin is one of the few effective antibiotics against multidrug-resistant bacterial infections, including carbapenem ...

mcr-1 Identified in Fecal Escherichia coli and Avian Pathogenic E. coli (APEC) From Brazil

Frontiers in Microbiology, 2021
Colisitin-associated resistance in bacteria of food producing animals has gained significant attention with the mcr gene being linked with resistance. Recently, newer variants of mcr have emerged with more than nine variants currently recognized. Reports

Analysis of Antimicrobial Resistance in Non-typhoidal Salmonella Collected From Pork Retail Outlets and Slaughterhouses in Vietnam Using Whole Genome Sequencing

Frontiers in Veterinary Science, 2022
Non-typhoidal salmonella (TS) remains a significant health burden worldwide. In Vietnam, pork accounts for 70% of the total meat consumed, and contamination with Salmonella is high. High levels of antimicrobial resistance (AMR) have emerged among porcine
