Set a thief…

BIOFILMS are a problem in medicine. When bacteria gang up to form the continuous sheets that bear this name they are far harder to kill with antibiotics than when they just float around as individual cells. Biofilms on devices such as implants are thus difficult to shift, and those growing on the surfaces of human organs are frequently lethal. But Matthew Chang, a biochemical engineer at Nanyang Technological University in Singapore, has worked out a new way to attack them. His weapon is a different type of bacterium, which he has genetically engineered into a finely honed anti-biofilm missile. (The Economist)
