Complete genome sequences and structural variants of pESI-like plasmids in multidrug-resistant Salmonella Infantis carrying blaCTX-M-65 from retail chicken meat in South Korea

These complete genome sequences expand the current knowledge of pESI-like plasmid diversity in S. Infantis and highlight their role in the dissemination of multidrug resistance in the poultry sector. Continued genomic surveillance is warranted to monitor the emergence and spread of high-risk S. Infantis clones across the food chain.
