Septic Stability? Gut Microbiota in Young Adult Mice Maintains Overall Stability after Sepsis Compared to Old Adult Mice

Older adults have worse outcomes after sepsis than young adults. Additionally, alterations of the gut microbiota have been demonstrated to contribute to sepsis-related mortality. We sought to determine if there were alterations in the gut microbiota with a novel sepsis model in old adult mice, which enter a state of persistent inflammation, immunosuppression and catabolism (PICS), as compared to young adult mice, which recover with the sepsis model.
