Zombie cells in the sea: Viruses keep the most common marine bacteria in check

[Science - Latest Science News -- ScienceDaily]

Marine microbes control the flux of matter and energy essential for life in the oceans. Among them, the bacterial group SAR11 accounts for about a third of all the bacteria found in surface ocean waters. A study now reveals that at times nearly 20% of SAR11 cells are infected by viruses, significantly reducing total cell numbers. The viruses can also transform these once thriving bacteria into zombies, a phenomenon observed for the first time and widespread in the oceans.
