    Abstract Over the past 10 years, microbiome research has focused on defining the structures associated with different disease states in multiple systems, but has fallen short on showing causation. Prior omic studies have generated many new hypotheses, but moving forward we need to start dissecting the function of each bacterium alone and in concert with complex bacterial communities in well-characterized systems. Over the next 5 years, we need a merging of new omic technologies for exploratory studies with classical bacterial genetics, bacterial physiology, protein engineering, and biochemistry to further define the biochemical mechanisms of the gut microbiota. The future of the systems microbiology field will focus on targeted engineering and editing of the microbiome to alter function, which will be leveraged to prevent and/or treat human diseases. This perspective will focus on my contribution to the microbiome field, both past and present, and where I think research in the field is headed in the near future.

    Abstract In this issue of Cell, Alavi et al. report that infection by Vibrio cholerae is blocked by gut microbiome-mediated hydrolysis of bile acids. Cholera therefore joins amebic dysentery and Clostridioides difficile colitis as enteric infections profoundly influenced by the microbiome's impact on bile acid metabolism.

    Abstract Clostridioides difficile is an urgent antimicrobial-resistant bacterium, causing mild to moderate and sometimes life-threatening disease. Commensal gut microbes are critical for providing colonization resistance against C difficile and can be leveraged as non-antibiotic alternative therapeutics for the prevention and treatment of C difficile infection.
