Kind: research · Impact: medium

## In brief

- A study published in the journal eBioMedicine reports that a "living medicine" thinned biofilms of antibiotic-resistant Pseudomonas aeruginosa in the lungs of pigs.
- The experimental treatment involves inhaling a genetically modified bacterium designed to target the biofilms.
- The findings come from animal experiments, so effects in humans have not been shown in these sources.

## Why it matters

Biofilms of drug-resistant bacteria are hard to clear with antibiotics, so a different approach that works in a large-animal model could inform future treatments for ventilator-associated lung infections.
