Can a Gut Test Detect Antibiotic Resistance? Understanding the Resistome

Can a Gut Test Detect Antibiotic Resistance? Understanding the Resistome

Each year, resistant bacteria contribute to millions of infections worldwide, making once-routine treatments increasingly difficult. While much of the conversation focuses on hospitals and infectious disease, researchers now recognize that the gut microbiome plays an important role in the ecology of antibiotic resistance.
