How Do Phages Work?
A specific bacteriophage seeks out host bacteria to which it is active, attaching itself to the exterior of the bacterial cell wall, and injecting its DNA into the bacterium. The phage’s DNA then highjacks the cell’s reproduction mechanism and reprograms it to produce bacteriophage particles. During this active infection process and after the phage has sufficiently multiplied and assembled phage progeny within the cell, enzymes are released by the phages which lyse the outer wall of the bacteria, killing the bacteria and releasing new bacteriophage into the environment to find and attack other bacteria of that type. Since phages multiply exponentially, a bacterial infection can be decimated in a very short amount of time.
