We may have found a way to kill drug resistant bacteria.

A new study from Brunel University found that saccharin, a common sugar substitute, can kill harmful bacteria and enhance the power of antibiotics.

The researchers discovered that saccharin damages the cell walls of multidrug-resistant bacteria, like E. coli and Staphylococcus aureus, leading to cell rupture and disrupted DNA replication.

This damage weakens bacterial defenses, allowing antibiotics to work more effectively. Saccharin also prevents the formation of biofilms—protective layers that help bacteria survive—which further boosts its infection-fighting potential.

In laboratory tests, a saccharin-based hydrogel outperformed silver-based dressings on pig skin models, suggesting new possibilities for treating infected wounds. While these results are promising, experts caution that more testing is needed to confirm safety and effectiveness in humans. There are still concerns about the broader health effects of artificial sweeteners, particularly on gut bacteria. Yet, given saccharin’s long-standing approval for human consumption, it could fast-track development and offer a powerful, low-cost weapon against a global antibiotic resistance crisis responsible for millions of deaths annually.
