Abstract
Rengarajan et al. show that stress in mice causes fecal dysbiosis, which is sufficient to induce diarrhea, intestinal barrier defect, and increased antibacterial IgA. IBS-D patients also display fecal dysbiosis and increased antibacterial IgA that is unique from healthy or IBD patients. This IgA response correlates with somatic symptom severity.
