Cholera-causing bacteria have defences that degrade plasmid invaders

Plasmids — circular DNA molecules — are found in many bacteria, and carry genes that can give the host microorganism new features. The mystery of how a cholera-causing bacterium eliminates plasmids has now been solved. Bacteria harbour two previously unknown anti-plasmid systems.
