Escherichia coli B-strains are intrinsically resistant to colistin and not suitable for characterization and identification of mcr genes

The paper shows that E. coli B-strains are intrinsically resistant to colistin and unsuitable for studying mcr genes due to inherent resistance mechanisms.

More than mcr: Canonical Plasmid- and Transposon-Encoded Mobilized Colistin Resistance (mcr) Genes Represent a Subset of Phosphoethanolamine Transferases

This study identifies and analyzes mcr-like genes, showing they are closely related to intrinsic lipid modification enzymes and evolve through positive selection and genomic context changes.

Monitoring the Antimicrobial Resistance Dynamics of Salmonella enterica in Healthy Dairy Cattle Populations at the Individual Farm Level Using Whole-Genome Sequencing

This study uses whole-genome sequencing to analyze Salmonella strains from dairy cattle farms, revealing AMR dynamics and evaluating in silico tools for serotyping and resistance detection.

The Typhoid Toxin Produced by the Nontyphoidal Salmonella Serovar Javiana Can Utilize Multiple Binding Subunits, which Compete for Inclusion in the Holotoxin

This study shows that S. Javiana's typhoid toxin uses multiple binding subunits that compete for inclusion in the holotoxin, enhancing toxin versatility.

Identification of novel mobilized colistin resistance gene mcr-9 in a multidrug-resistant, colistin-susceptible Salmonella enterica serotype Typhimurium isolate using a combination of high-throughput, in silico screening and functional analysis

The paper identifies a novel mcr-9 gene in a multidrug-resistant Salmonella isolate using in silico screening and functional analysis, showing it confers colistin resistance in E. coli.
