Microbes Scared to Death by Virus Presence

The microbes could surrender to the harmless virus, but instead freeze in place, dormant, waiting for their potential predator to go away, according to a recent study in mBio.

University of Illinois researchers found that Sulfolobus islandicus can go dormant, ceasing to grow and reproduce, in order to protect themselves from infection by Sulfolobus spindle-shaped virus 9 (SSV9). The dormant microbes are able to recover if the virus goes away within 24 to 48 hours—otherwise they die.
