Abstract

Elevated microbial bile salt hydrolase (BSH) activity is associated with significant alterations in host functions related to lipid metabolism and weight gain.

  • BSH activity leads to local bile acid deconjugation in the gastrointestinal tract.
  • Changes in lipid and cholesterol metabolism are observed with increased BSH expression.
  • Key factors involved in cholesterol balance and gut health are influenced by elevated BSH.
  • The findings suggest a potential link between gut microbiota activity and host weight gain.
