Why do some people get sepsis while others don't? Scientists point to the gut

Potentially deadly sepsis may be more likely in certain patients due to problems in the gut.

Researchers from the Korea Research Institute of Bioscience and Biotechnology's Infectious Disease Research Center used female mouse models to investigate why sepsis outcomes can vary so dramatically.

The study, published in the journal Nature, looked at genetically similar mice with different gut microbiomes. The mice were infected with Acinetobacter baumannii — a highly resilient bacterium that can lead to sepsis.
