Lead researcher Dr Dale Boger explained: "We made one change to the molecule vancomycin that overcomes what is the present resistance to vancomycin. And then we added to the molecule, two small changes that built into the molecule, two additional ways in which it can kill bacteria. So the antibiotic has three different, we call them 'mechanisms', by which it kills bacteria. And resistance to such an antibiotic would be very difficult to emerge. So it's a molecule designed specifically to address the emergence of resistance."
