9: Phage Therapy
Maybe you’ve had the experience of being sick, and your doctor struggling to find the right antibiotics to treat your infection. Or maybe you had to restart your treatment with different antibiotics because the first ones didn’t work.
Situations like this are becoming more and more common, as antibiotic-resistant bacteria continue to spread. At the same time, new antibiotics are being developed very slowly.
So the question is: could there be another solution?
Another way to treat bacterial infections?
One possibility is to use the natural predators of bacteria: viruses that specifically infect bacteria and destroy them. And what might surprise you is that this is not some futuristic idea. It’s an approach that has already been used to successfully treat patients, and it was developed more than a hundred years ago.
As you probably guessed by now (and, well… as the title says), today’s episode is all about phage therapy.
