Microbiome signature of posttraumatic stress disorder and resilience in youth.

Our findings provide evidence that the trauma-associated microbiome profile is at least partially responsible for the anxiety component of the PTSD phenotype and highlight microbial underpinnings of resilience. Further, our results suggest that the microbiome may serve as additional biological memory of early life stress and underscore the potential for microbiome-related diagnosis and treatment following trauma.
