Speaking at the Society for General Microbiology's spring meeting in Edinburgh, Dr Kristine Arnvig provides further insight into how the bacterium causes tuberculosis (TB) by fine-tuning its behaviour in response to its surroundings to escape detection. Understanding the genetic tools and tricks used by Mtb to control its behaviour is likely to give an idea how it manages to survive for such long periods...
