CRISPR “Gene Drive” Reverses Antibiotic Resistance in Bacteria

Population-wide editing system strips resistance genes – even inside hard-to-treat biofilms

1

A CRISPR-based system can reverse antibiotic resistance in bacteria by removing resistance genes instead of killing the bacteria.
2

The new tool, pPro-MobV, enhances gene transfer through a conjugation-based system, allowing efficient spread among bacterial cells.
3

Laboratory experiments demonstrated a reduction of antibiotic-resistant bacteria by three to five orders of magnitude.
4

The system effectively targets biofilms, which are challenging to eliminate and often associated with chronic infections.
5

The platform includes a safeguard for gene removal and potential applications in clinical, environmental, and industrial settings.
