Control of Bacterial Biofilm Formation

  • Control of Bacterial Biofilm Formation
  • With up to 1000 times higher tolerance to antibiotics and disinfectants compared to their planktonic counterparts, biofilms of pathogenic bacteria cause chronic infections in humans with high mortality and morbidity. Such infections cause billions of dollars of losses and more than 45,000 deaths annually in the U.S. alone. With the efficacy of antibiotics being intrinsically limited, new approaches especially those with synergistic effects are desired. The Ren lab in BMCE department has board interests in biofilm control including the genetic basis of multidrug resistance, development of novel biofilm sensors, biofilm control through surface engineering and development of novel biofilm inhibitors.
