Traumatic injury disrupts the gut microbiome, leading to immune dysfunction. This review explores post-injury microbiome changes, their mechanisms, and potential therapies like fecal transplantation for recovery.
Area of Science:
- Microbiology
- Immunology
- Gastroenterology
Background:
- The intestinal microbiome is vital for immune function and host homeostasis.
- Traumatic injuries can lead to immune dysregulation and systemic inflammation.
- Studies show trauma alters gut microbiome diversity and composition, creating a pathobiome.
Purpose of the Study:
- To review gut microbiome alterations following traumatic injury.
- To explore proposed mechanisms driving these changes.
- To discuss future research directions and therapeutic interventions.
Main Methods:
- Literature review of studies on traumatic injury and the gut microbiome.
- Analysis of research investigating immune function and inflammation post-trauma.
- Examination of sex as a biological variable in microbiome alterations.
Main Results:
- Traumatic injury induces significant changes in gut microbiome diversity and composition.
- A shift towards a pathobiome state is observed after injury.
- Sex influences the specific alterations in the microbiome post-trauma.
Conclusions:
- Gut microbiome dysbiosis is a key consequence of traumatic injury.
- Understanding these changes is crucial for developing effective recovery strategies.
- Therapeutics like fecal transplantation show promise for mitigating microbiome damage and improving outcomes.

Anatomy of the Intestines
Small Intestines
The small intestine is an ~7 meter-long tube with an inner diameter of just 2.5 cm. Since most nutrients are absorbed here, the inner lining of the...
Bacterial Flora of the Large Intestine
The normal gut flora of the colon plays a critical role in generating essential vitamins such as vitamins K, B5, and B7.
Defense Mechanism Against Infection
In addition, many body organ systems have unique defenses against infection. The skin is an intact, multilayered surface preventing invasion by microorganisms unless impaired. Mucous membranes lining the mouth, nose, and eyelids are barriers...
