Plasmids promote antimicrobial resistance through Insertion Sequence-mediated gene inactivation.
Combining experimental and computational approaches, we unveil how two of the most prevalent bacterial MGE accelerate the evolution of AMR. 🧵👇🏻

Bacteria chromosomes contain Genomic Islands that provide virulence, antibiotic resistance, MGE-defence,... They transfer between cells, but the mechanism of most remains elusive.
Here we explore the conjugative capacity of these mysterious Genomic Islands.
