Study uncovers how the body's bile acids bind to block C. diff's most dangerous toxin

In a major step towards a precision therapy for Clostridioides difficile (C. diff) infection, researchers at The Hospital for Sick Children (SickKids) have uncovered how the body's bile acids bind to block C. diff's most dangerous toxin.

Industrial and farm chemicals quietly alter the balance of gut microbes

This study systematically screened over 1,000 agricultural and industrial chemicals and found that many can inhibit human gut bacteria in vitro. Beyond antimicrobial effects, these chemicals act as selective pressures that can reshape microbial competition, tolerance mechanisms, and metabolic pathways.
