In this seminar, construction methods and working principles of bacteria which can detect and record environmental signals in the mammalian gut are explained. The ability of engineered bacteria to report on enviromental cues in variable and incompletely understood environment has implications for development of new ways of diagnostics. For example, bacteria native to the human gut or skin might be used to monitor exposure to chemicals characteristic of specific disease state. The system described here is sufficiently modular that the trigger and memory circuits could be reengineered to respond to chemical signatures of inflammation, cancer, parasites, or presence of toxins in the gut. In combination with additional genetic circuits, such as the recent search-and-destroy circuits, bacteria could be designed with the memory element that can diagnose a specific pathogen and emit a therapeutic. Together these approaches may allow construction of a new class of engineered probiotic bacteria that could have wide diagnostic and therapeutic application.
