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

Cristobal Martinez-Padilla, Daniel Tichy-Navarro, Rocío Barrón-Montenegro…·Alejandro Piña-Iturbe

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.

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

Alejandro Piña-Iturbe, Constanza Díaz-Gavidia, Francisca P. Álvarez…·Andrea I. Moreno‐Switt

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.
