Emergence and Dissemination of mcr-Carrying Clinically Relevant Salmonella Typhimurium Monophasic Clone ST34
Antibiotic resistance in bacteria is one of the urgent threats to both public and global health. The Salmonella Typhimurium monophasic sequence type 34 (ST34) clone, with its rapid dissemination and resistance to numerous critical antimicrobials, has raised global concerns. Here, we present an updat...

description | Antibiotic resistance in bacteria is one of the urgent threats to both public and global health. The Salmonella Typhimurium monophasic sequence type 34 (ST34) clone, with its rapid dissemination and resistance to numerous critical antimicrobials, has raised global concerns. Here, we present an updated overview on the emerging infections caused by mobile colistin resistance (mcr)-carrying colistin-resistant ST34 isolates, covering their global dissemination and virulence-associated efficacy. The higher rates of mcr-1-positive ST34 in children in China highlights the increasing threat caused by this pathogen. Most of the ST34 isolates carrying the mcr-1 gene were isolated from animals and food products, indicating the role of foodborne transmission of mcr-1. The emergence of multidrug resistance genes along with various virulence factors and many heavy metal resistance genes on the chromosome and plasmid from ST34 isolates will challenge available therapeutic options. The presence of the colistin resistance gene (mcr-1, mcr-3, and mcr-5) with the multidrug-resistant phenotype in ST34 has spread across different countries, and most of the mcr-1 genes in ST34 isolates were detected in plasmid type IncHI2 followed by IncI2, and IncX4. Together, mcr-carrying S. Typhimurium ST34 may become a new pandemic clone. The fast detection and active surveillance in community, hospital, animal herds, food products and environment are urgently warranted. |
