This paper shows that IscR, an iron-sulfur cluster sensor, regulates virulence gene expression in Yersinia pseudotuberculosis by responding to iron and oxygen levels, with mutations altering infection dynamics.

This study identifies PAPI (encoded by pcnB) as essential for maintaining virulence and AMR plasmid copy number, stability, and bacterial virulence in Yersinia and Shigella.
