As bacterial cells within a cluster or swarm die, they release chemical death cries, which scientists call necrosignaling. These signals act like a kind of early warning system, allowing the surviving bacterial cells to prepare a type of resistance to antibiotics. The process of necrosignaling is outlined in a new paper out today in …read more
