Biologists Program E. Coli To Patrol For Pathogens

MTorrice writes "When hospital patients develop nasty, antibiotic-resistant infections, the bacterium Pseudomonas aeruginosa is often the culprit. In a new approach to killing the pathogen, researchers genetically modified harmless Escherichia coli bacteria to detect and destroy P. aeruginosa. The E. coli spot a specific chemical released by the pathogen and then secrete a toxin to kill it (abstract)."
