Could topping up the bacteria in our guts help us recover from injuries quicker? Scientists at Rockefeller University studying mice with spinal cord injuries found that the injury altered the bacteria in the guts of the mice, prompting the release of inflammatory cells. This initiated other processes that impaired their ability to recover from the injury. When some mice were treated with probiotics, they recovered from their injuries faster. The study’s authors suggest that when treating spinal cord injuries in humans, changes in the gut could be counteracted with probiotics to assist with recovery.
