Acerca de esta escucha
Are native chickens really antibiotic-free? In this episode, microbiologist Dr. Rina Opulencia breaks down her research on multidrug-resistant (MDR) bacteria found in healthy Philippine native chickens. Her team sequenced bacterial genomes and discovered antibiotic resistance genes in Philippine native chickens, which raises important questions about farm hygiene and food safety. Learn how resistance spreads, what mobile genetic elements do, and what this means for farmers, consumers, and policy.
