Prophage {Phi}ESI promotes competitive dominance in the emergent Salmonella serovar Infantis lineage

This paper identifies {Phi}ESI, a prophage in Salmonella Infantis, as a competitive factor that helps the emergent lineage outcompete non-emergent strains by selectively lysing susceptible competitors.

Emergence of a multidrug-resistant Salmonella enterica serovar Amager lineage carrying the blaCTX-M-65-positive pESI megaplasmid

The paper characterizes a multidrug-resistant Salmonella Amager strain carrying a blaCTX-M-65-positive plasmid, highlighting its emergence and potential for human infections.

Emergent Salmonella enterica serovar Infantis forms a monophyletic lineage shaped by geographic structuring

The paper analyzes global Salmonella Infantis genomes to show a monophyletic lineage shaped by geographic structuring and links its spread to antibiotic resistance gene dissemination.

Widespread dissemination of ESBL-producing Salmonella enterica serovar Infantis exhibiting intermediate fluoroquinolone resistance and harboring blaCTX-M-65-positive pESI-like megaplasmids in Chile

This study sequenced 396 Salmonella Infantis genomes from Chile, revealing widespread dissemination of MDR isolates associated with ESBL-producing plasmids and intermediate fluoroquinolone resistance across multiple niches.
