Antibiotic-resistant superbugs are spreading in hospitals, a Europe-wide study has revealed. The spread of antibiotic-resistant Klebsiella pneumonia is "extremely concerning," say researchers. Klebsiella pneumonia can live in the intestines undetected for healthy people. But during times of sickness, the bacteria can infect the lungs, blood and brain, causing pneumonia or meningitis. Deaths from K. pneumonia increased from 341 in Europe in 2007 to 2,094 by 2015. Dr Sophia David, Sanger Institute, via BBC.
