6-year study links less healthy gut flora to increased risk of serious infections, including pneumonia, due to reduced butyrate-producing bacteria.

6-year study of 10,000 people reveals a link between less healthy gut flora and increased risk of serious infections like pneumonia. Researchers found that those with less butyrate-producing bacteria in their microbiome were more likely to develop a severe infection, which in some cases led to death. The results were published in The Lancet Microbe. (Summary length: 217 characters)
