Although the mechanism of bacterial chemotaxis has been extensively studied in enteric bacteria, the hunt for novel and atypical chemoeffectors (in enterics and distantly-related species alike) has necessitated the modification of classic chemotaxis assays to deal with recalcitrant and potentially toxic chemicals. Here, we describe detailed protocols for the quantitative and qualitative assessment of chemotaxis responses that are categorized into short-term direct population response assays and long-term metabolism-based assays that can be used to identify novel chemoeffector molecules and the specific chemoreceptors involved. We emphasize the importance of behavior-based assays to verify the biochemical and physiological relevance of newly identified chemoeffector-receptor pairs.
