People who are bedridden, have circulation problems or have diabetes often develop sores that won’t heal. If infection sets in, people may die or need to have limbs amputated. Most current therapies, including antibiotics, don’t work well, says Manuela Martins-Green, a cell biologist at the University of California, Riverside.
