A newly discovered form of immunity helps explain how bacteria fight off viruses

A newly discovered form of immunity helps explain how bacteria fight off virusesScientists have discovered an immune-defense mechanism in bacteria that allows these microorganisms to respond to viral infections with remarkable precision. Their findings could have implications for the development of new therapies against infectious diseases. More »

Rockefeller scientists resolve long-standing debate over how many bacteria fight off invaders

For years, researchers have puzzled over conflicting results about the workings of type III CRISPR-Cas systems, a type of immune system found in many species of bacteria. Some data showed that this mechanism would target the virus’s DNA, while other experiments suggested it could only disable a virus once it had started replicating itself. New results suggest both mechanisms play a role.

Discovery reveals how bacteria distinguish harmful versus helpful viruses

Discovery reveals how bacteria distinguish harmful versus helpful virusesViruses can kill bacteria, or viruses can help the microbes by lending them potentially useful genes. New research shows Staph bacteria have an immune system capable of distinguishing dangerous invaders from potentially beneficial ones. More »
