Science in Seconds - Antibiotic Resistance

0 (0 Likes / 0 Dislikes)
Science in Seconds Know Everything RANTS - Antibiotic Resistance Torah Kachur: Antibiotics are one of the most impressive and useful discoveries of modern medicine. These naturally occurring substances kill off bacteria without harming human cells. They are so great that we use them all the time for sore throats, colds, flus, stress, acne, and a thousand other uses they do nothing for. Antibiotics are incredibly effective in killing off bacterial cells. Only bacterial cells. Not viruses. Not fungal infections. Not allergic reactions. Only bacteria. The overuse of antibiotics in agriculture and over-prescription by doctors is the major factor in the surge in antibiotic-resistant bacteria now attacking our health-care system. Superbugs like MRSA and C. difficile are causing up to a fivefold increase in the risk of death from infections in hospitals than their antibiotic-sensitive counterparts. Outbreaks of these superbugs in hospitals have caused deaths around the globe, and they really piss off hospital administrators. Antibiotic-resistant bacteria come from exposure to antibiotics. Bacteria divide at least every hour, which means they can evolve way faster than any human by accumulating potentially beneficial mutations. If we challenge a bunch of bacteria to survive by exposing them to unnecessary antibiotics, the one that has natural resistance will take up that challenge and pass its genes on to create new superbug progeny. The bacteria will always win the evolutionary race with humans. So the more we challenge bacteria with prescriptions for "boo-boos", or colds, or pumping our livestock full of antibiotics the longer the bacteria have to figure out ways to become resistant. For once, resistance is not futile. Courtesy of Science in Seconds – All rights reserved Only for educational/non-profit purposes. (Translators are invited to put their name here)
