Study reveals hidden gut factor that may make some people more susceptible to sepsis

A study by the Korea Research Institute of Bioscience and Biotechnology found that mice with higher concentrations of Muribaculaceae bacteria in their gut, particularly Sangeribacter muris KT1-3, were more susceptible to severe sepsis after infection with Acinetobacter baumannii. The research suggests gut microbiome composition influences immune system reactivity, leading to worse survival outcomes in sepsis.
