New technology developed for building custom viruses

Bacteriophages, or phages, are naturally occurring viruses that can kill bacteria. Scientists are trying to biologically engineer bacteriophages in order to fight bacterial infections. Now, a team of researchers from ETH Zurich has just presented a new technology that enables the production of genetically modified viruses. The viruses are thus provided with additional properties and then, once delivered in the host cells, they can be activated. The tool is extremely powerful and also quick, allowing scientists to create almost any type of bacteriophage. The new technique may enable the destruction of harmful bacteria, difficult to target otherwise, as in the case of antibiotic-resistant bacterial strains.
