I post this because I find many people, including some doctors, know little about the topic, and I think it interesting and possibly important.
Phages: the tiny viruses that could help beat superbugs
Bacteriophages were superseded by modern antibiotics, but scientists believe they could be key to conquering antimicrobial resistance
Discovered in 1917 by French Canadian biologist Félix d’Hérelle, phages – or bacteriophages – are tiny viruses that are natural predators of bacteria. In many countries they were supplanted during the second world war by antibiotics but continued to be used for decades in eastern Europe.
They are now being seen by some scientists as a complement – and perhaps an alternative –to antibiotics, the overuse of which has led to increasing bacterial resistance and the advent of the superbug.
I am adding a link to the Wikipaedia entry for the curious.
