Antibacterial drug combinations and evolution of drug resistance
Remy Chait, Harvard Systems Biology
April 24, 2007
The rapid evolution of bacterial drug resistance and the alarming slowdown in development of new antibiotics is spurring attention towards multi-drug treatments.

I will present a simple model and direct experimental measurements showing that non-additive interactions between the drugs can profoundly alter the fitness landscape, leading to surprising and counterintuitive outcomes.
