Viruses that infect bacteria are among the most abundant life forms on Earth. Indeed, our oceans, soils and potentially even our bodies would be overrun with bacteria were it not for bacteria-eating viruses, called bacteriophages, that keep the microbial balance of ecological niches in check.¬†Now, a new study suggests that bacteriophages made of RNA — a close chemical cousin of DNA — likely play a much larger role in shaping the bacterial makeup of worldwide habitats than previously recognized.

Bacteriophages are viruses that infect and kill bacteria. The name originates from the Greek ‘phagos’ which means ‘to devour’.¬†Bacteriophages were discovered 100 years ago because of their ability to replicate in a pathogenic bacterium, kill it and thereby cure the patient. As a small spaceship landing on the moon, the microscopic particles land on the surface of the bacteria where they inject their deadly genetic material.
