Chromosomal integration of blaCTX-M redefines the evolutionary trajectory of antibiotic resistance in E. coli through lineage-structured expansion

Maxime Danjean, Thibaut Morel‐Journel, Valentine Berti…·Laurence Armand-Lefèvre

The paper identifies chromosomal integration of blaCTX-M in E. coli, showing lineage-specific prevalence and suggesting it contributes to the spread of antibiotic resistance.

Influence of iron uptake systems on cefiderocol activity in Escherichia coli: at the crossroads of antibiotic resistance and virulence

Emilie Mallecot, Valentine Berti, Marie Petitjean…·Laurence Armand-Lefèvre

This study examines how iron uptake systems affect cefiderocol activity in E. coli, showing that the fec operon increases resistance and is linked to virulence.
