Weizmann Institute researchers have identified three new families of proteins that viruses use to disrupt bacterial immune signaling

An electron microscope view of phages duplicated inside bacterial cells that possess the immune system discovered in the new study. This immune system attaches a ubiquitin-like protein (marked by black dots and white arrows) to the tails of these phages, preventing them from infecting other bacterial cells
