Summary

Scientists have uncovered new details about how bacteria share genes, including those that drive antimicrobial resistance (AMR), a growing global health threat. The findings come from researchers at the John Innes Centre, who studied unusual particles known as gene transfer agents (GTAs). GTAs resemble bacteriophages (viruses that infect bacteria), but they are no longer harmful invaders. Instead, they are derived from ancient viruses that bacteria have adapted and brought under their own control.
