A vaccine that can protect against infection with the skin bacterium Staphylococcus aureus, which causes everything from wound and joint infections to impetigo and pneumonia, has been developed by scientists in the US. Apart from increasing rates of antibiotic resistance, what makes Staph infections hard to treat is that the microbes surround themselves with a slimy layer called a biofilm that protects them from the immune system and antimicrobial drugs. As she explains to Chris Smith, to prevent the bugs being able to do this in the first place, Janette Harro looked at what proteins the bacteria produce when they infect, and has turned these into a vaccine…
