Antibiotics are losing ground. Bacteria are evolving resistance faster than new drugs are being developed, and the problem is worst in chronic infections, such as long-lasting wound and lung infections, that persist for months or years despite treatment.

What they work on

  1. Identify vulnerability tradeoffs, weaknesses that appear when antibiotic-resistant bacteria reshape their physiology to survive drug exposure, and test whether targeting them clears infection in a mouse chronic wound model.
  2. Build multi-species wound pathogen community models and use them to measure how bacterial interactions shift antibiotic effectiveness, with a method the team proposes could be adapted for clinical labs.
  3. Design combination antibiotic treatments that exploit polymicrobial antagonism, where mixed communities become more drug-sensitive, to overcome synergism that protects bacteria, and validate them in a mouse wound infection model.

More about the research

Each failed attempt to clear these infections gives bacteria another chance to evolve new ways around the drugs. This project asks how features of the chronic infection environment could instead be turned against the bacteria, so that the antibiotics already in use keep working longer.

Why it matters

People with chronic wound and lung infections can carry bacteria for months, years or even decades, and prolonged, failing antibiotic treatment helps resistance spread among dangerous pathogens. Treatment strategies tailored to the chronic infection environment, such as drug combinations that exploit bacterial weak points or interactions between species, could make existing approved antibiotics work for longer. The proposed lab method for measuring how mixed communities change drug effectiveness may also help clinical labs guide treatment choices.
