" Researchers at Aberystwyth University have taken a step closer to developing a new, more effective vaccine against tuberculosis (TB), a disease that kills around 1.7 million people around the world every year. The Aeras Global TB Foundation has discovered a protein that &amp;#039;wakes up&amp;#039; dormant versions of the bacterium that causes TB. The bacterium, Mycobacterium tuberculosis, was responsible for up to 25 per cent of deaths in Europe during the 19th century. Scientists hope to develop a vaccine that either prevents TB bacteria from taking hold, stops dormant bacteria from waking up, or deliberately wakes up these bacteria in a controlled way so that they can be destroyed with antibiotics. Professor Mike Young, who is based in Aberystwyth University&amp;#039;s newly formed Institute of Biological, Rural and Environmental Studies, commented: &amp;#039;Current TB treatments can go on for over six months and can still leave bacteria in the body that can cause the disease when they resume active growth and multiplication. &amp;#039;Our discovery, which is now being developed into a vaccine, might help prevent the establishment of persistent infections in the first place or, alternatively, it might prevent persisting organisms in individuals with latent TB from reawakening at all.&amp;#039; \u00A9 Adfero Ltd "^^<http://www.w3.org/2001/XMLSchema#string>
