Distinct plasmid- and host-encoded mechanisms drive small plasmid copy number-mediated heteroresistance in Escherichia coli

Angelika Ntokaki, Enrique Joffré, Bart Melgers…·Helen H. Wang

The paper shows small plasmids can cause antibiotic heteroresistance through copy number increases via plasmid mutations or chromosomal recD mutations in Escherichia coli.

The pcnB gene sustains Shigella flexneri virulence

Thibault Frisch, Petra Geiser, Margarita Komi…·Maria Letizia Di Martino

The paper shows that the pcnB gene in Shigella flexneri promotes virulence by sustaining optimal levels of the virulence plasmid pINV, enhancing colonization and infection.
