Researchers have discovered a faster, cheaper method for the diagnosis of tuberculosis (TB). A major barrier in TB prevention, especially in developing countries, is that diagnosis is slow and costly. Dr Olivier Braissant and his colleagues have developed a method which could potentially decrease the time taken to make a diagnosis. Their method is also cheaper than the current fastest methods. This research has been published today in the Society for Applied Microbiology’s Journal of Applied Microbiology.
