What to know about Immunology Research

Researchers from the University of Bristol and the University of Surrey have discovered that sodium butyrate, a naturally occurring gut molecule, can program chicken immune cells to better fight bacterial infections. The study, published in The Journal of Immunology, suggests a potential method for reducing the poultry industry's reliance on antibiotics to combat antimicrobial resistance.
