The Challenge of Antibiotic-Resistant Superbugs
Ever since penicillin was discovered, scientists have realized that bacteria could develop resistance to antibiotics. In the last decade or so, these fears have become more acute. Many dangerous pathogens have evolved to become resistant to multiple antibiotics. Some have become impervious to drugs that are generally reserved for last-resort use. With the common use of many antibiotics to promote animal growth and weight gain in agriculture, antibiotic-resistant microbes are showing up in all sorts of unexpected places, not just in hospitals. What can be done about these superbugs?
Why Is There Antibiotic Resistance?
Our guests describe the problem of antibiotic resistance and discuss what we as individuals can do to keep from contributing to the crisis. When is it safe for parents to hold off on giving antibiotics to a sick child? What else can we do to lower the footprint of antibiotics in the world? Renouncing routine use of antibiotics to speed the growth of livestock and poultry might be one important step.
A Novel Way to Overcome Superbugs:
One of our guests, Dr. Paul Turner, is working on ways to turn the millennia-old war between viruses and bacteria to our advantage. Phage therapy began early in the 20th century, before antibiotics were common. What contributions can it make now, when so many bacteria are evolving to show resistance to our powerful modern compounds?
For a fascinating demonstration of how bacteria develop antibiotic resistance to become superbugs, you may wish to watch this video.
Here’s a current story from the Los Angeles Times demonstrating how perplexing and serious the problem of superbugs can be.
