Antibiotics are becoming less and less useful, and people are dying because of it. Drug resistance in bacteria is one of the possible game-changers for this century, but a new line of research could push that problem back by a decade or two.
Bacteriophages are viruses that prey on bacteria. They work the same way that other viruses do – injecting genetic material into a cell to make it produce more viruses. If scientists can engineer varieties of phages that can inject genetic material into bacteria that either kills them or reduces their drug resistance, then we have a new way to keep the bugs in check.
