Bacterial chemotaxis towards compounds in the gut

Over the past two decades, the new field of microbial endocrinology has been increasing with new discoveries that highlight the role of the host-microbiome interactions in critical processes. The current study starts to unravel the chemotactic responses of a model commensal bacterium Escherichia coli to compounds present in the gastrointestinal tract, as well as to investigate the effects of these substances on the physiology of bacteria.
