Salmonella Typhimurium DT104 is an aggressive type of bacteria, which is particularly problematic because it has developed resistance to a number of antimicrobials and has been able to quickly spread throughout the world. Using new technology the National Food Institute, Technical University of Denmark, has been able to trace the bacteria back to its origin and work out when it developed resistance. The technology can likely be used to monitor new bacterial strains, prevent and not least understand infectious diseases.
