Scientists discover unusual bacterial defense that triggers self-destruction during infection

Scientists have identified a unique bacterial defense system that operates in a way unlike previously known mechanisms, according to ScienceDaily Health.

Typically, bacterial immune systems keep a deadly toxin in check until a virus attacks, but this new system waits until an infection begins before activating its lethal weapon.

Once the infection starts, the bacterium produces DNA that triggers self-destruction, effectively preventing the virus from spreading to nearby cells.

This discovery reveals a novel approach bacteria use to defend themselves by sacrificing infected cells to protect the larger population.
