Researchers deploy bacteriophages to fight against antibiotic resistance
Bacteriophages kill bacteria through different mechanisms than antibiotics, and they can target specific strains, making them an appealing option for potentially overcoming multidrug resistance. However, quickly finding and optimizing well-defined bacteriophages to use against a bacterial target is challenging.
In a new study, MIT biological engineers showed that they could rapidly program bacteriophages to kill different strains of E. coli by making mutations in a viral protein that binds to host cells. These engineered bacteriophages are also less likely to provoke resistance in bacteria, the researchers found.
