Most of the anti-phage defense systems of bacteria can be described as a combination of two main components.

Second, an effector component that mediates the immune response following the detection of phage infection.

The effector components of anti-phage systems are very diverse, and can be arbitrarily distributed in broad categories :ref{doi=10.1038/s41579-023-00934-x} :
