and female) were fed AIN93M diet supplemented with 15% freeze-dried watercress (w/w).Composition of the fecal microbiota was determined by shotgun metagenomics sequencing and differential abundance of taxa was analyzed using the One Codex microbiome analysis platform.Results: Treatment with freeze-dried watercress altered the relative abundance of bacterial genera and species within the fecal microbiome.For example, consumption of freeze-dried watercress increased abundance levels of Parasutterella excrementihominis, Bacteroides thetaiotaomicron, and Akkermansia muciniphila.Conclusions: Treatment with freeze-dried watercress modulated the gut microbiota composition at the genus and species levels.
