Overview

Genomic analysis reveals an XDR Salmonella Kentucky isolate with multiple antibiotic resistance genes, highlighting food safety risks.

Key Points

  • The study identifies a unique isolate of salmonella co-harboring multiple resistance genes, leading to extensive drug resistance.
  • Genomic analysis revealed that the isolate was resistant to 21 antibiotics, including last-resort drugs like colistin and tigecycline.
  • Genomic characterizations emphasized the role of plasmids in transferring resistance genes among bacteria, raising public health concerns.
  • This research represents the first report of an extensively drug-resistant salmonella isolate originating from poultry meat in Shanghai.
