Stopping Superbugs

E. coli bacteria (c) NIAID

What is the scale of the superbug problem? How much is antibiotic resistance costing? Can new antibiotics be made that cannot be bypassed by bacteria? And what new drugs are already in the pipeline. In this infectious episode of the Naked Scientists, we put the rise of antimicrobial resistance under the microscope and ask what scientists are doing to combat the problem. Plus, why the abominable snowman hasn't been discovered...yeti, 46-million-year-old blood from a fossilised mosquito, phage therapy for C. diff and the brain wash-out that happens when we sleep...
