Since the advent of penicillin more than 90 years ago, antibiotic drugs have saved countless lives by preventing and treating bacterial infections. However, bacteria are rapidly developing new ways to resist antibiotics, making some of modern medicine’s most powerful drugs less effective against many life-threatening infections, such as gonorrhea, Methicillin-resistant Staphylococcus aureus (MRSA) and Clostridioides difficile (C. difficile), among others. Today, the Centers for Disease Control and Prevention (CDC) estimate nearly 3 million drug-resistant infections occur each year in the United States alone.
