Curli-independent defense against <i>Bdellovibrio bacteriovorus</i> in <i>E. coli</i>.

ABSTRACT: Predatory bacteria are a group of organisms that use diverse methods to access nutrients and grow by killing prey bacteria. The predator Bdellovibrio bacteriovorus is capable of preying on a wide range of gram-negative bacteria by invading the periplasmic space, killing, digesting, and ultimately lysing prey cells. B. bacteriovorus, like a phage, replicates at the expense of its host, yet unlike phage defense, there are few characterized mechanisms for bacteria to resist B. bacteriovorus. Previously, we discovered that an extracellular amyloid protein called curli protects Escherichia coli from B. bacteriovorus. Here, we searched for additional modes of B. bacteriovorus resistance and identified a strain within the E. coli Reference (ECOR) c
