Bacteriophage resistance

Bacteriophage attacking a cell Phages are now acknowledged as the most abundant microorganisms on the planet and are also possibly the most diversified. This diversity is mostly driven by their dynamic adaptation when facing selective pressure such as phage resistance mechanisms, which are widespread in bacterial hosts. When infecting bacterial cells, phages face a range of antiviral mechanisms, and they have evolved multiple tactics to avoid, circumvent or subvert these mechanisms in order to thrive in most environments. This review highlights the most important antiviral mechanisms of bacteria as well as the counter-attacks used by phages to evade these systems.
