Bacteria Uses Viral Weapon Against Other Bacteria
Published:04 Jun.2019    Source:Phys.org

Bacterial cells use both a virus—traditionally thought to be an enemy—and a prehistoric viral protein to kill other bacteria that competes with it for food according to an international team of researchers who believe this has potential implications for future infectious disease treatment. The team, led by Thomas Wood, holder of the biotechnology endowed chair and professor of chemical engineering, Penn State, noticed a gap between two kinds of bacterial cells as they moved on agar plates toward each other, in a form of motility known as "swimming" where the bacterium moves by rotating its flagella.
