Phylogenetic analysis reveals intercontinental spread of plasmid-borne multidrug-resistant Salmonella Infantis in poultry and humans, highlighting food trade as a transmission route.

Key Points

Multidrug resistance in Salmonella Infantis spreads via a shared IncFIB replicon, with European and Brazilian poultry isolates forming tightly connected global genetic lineages.
Nearly half of examined isolates, exactly 194 of 417, harboured the IncFIB replicon linked to antimicrobial resistance genes, which first emerged in Europe during the late 1980s.
Phylogenetic analysis and genetic clustering tracked 417 bacterial isolates from Europe and the Americas, comparing short-read data with hybrid long-read plasmid assemblies.
Highlights the critical need for hybrid genomic sequencing to locate antimicrobial resistance plasmids, while showing that international poultry trade spreads persistent pathogens.
