Länk - Om man blockerar bakteriers kväveoxidproduktion kan antibiotika börja fungera igen
Nudler's team found that many antibiotics kill bacteria through the production of harmful charged particles known as reactive oxygen species, otherwise called oxidative stress. "Antibiotics cause bacteria to produce a lot of reactive oxygen species. Those damage DNA, and bacteria cannot survive. They eventually die," says Nudler. "We found nitric oxide can protect bacteria against oxidative stress." He says bacteria produce nitric oxide to resist antibiotics. The defence mechanism appears to apply broadly to many different types of antibiotics.
