Viruses of bacteria (bacteriophages or phages) are highly evolved nanomachines that recognize bacterial cell walls, deliver genetic information, and kill or transform their targets with unparalleled specificity. For a long time, the use of genetically modified phages was limited to phage display approaches and fundamental research. This is mostly because phage engineering has been a complex and time-consuming task, applicable for only a few well characterized model phages. Recent advances in sequencing technology and molecular biology gave rise to rapid and precise tools that enable modification of less-well-characterized phages. These methods will pave the way for the development of modular designer-phages as versatile biologics that efficiently control multidrug-resistant bacteria and provide novel tools for pathogen detection, drug development, and beyond.
Keywords: bacteriophage; genome engineering; phage therapy; synthetic biology.
