This video introduces our engineered ECN-1917, which integrates the Salmonella AI-2 quorum sensing reception system and the disease-characterizing compound tetrathionate recognition system. We have endowed the engineered bacteria with the ability to early diagnose gastrointestinal infection signals, which can be identified through a simple LacZ colorimetric reaction. Additionally, the video also explains how we repair potentially damaged intestinal barriers with defensins to resist pathogen infections.
