Diffusible signaling factor interferes with and is toxic towards Bdellovibrio bacteriovorus 109J

Bdellovibrio bacteriovorus 109J is a predatory bacterium which lives by predating on other Gram-negative bacteria to obtain the nutrients it needs for replication and survival. Here, we evaluated the effects a bacterial signaling molecule called diffusible signaling factor (DSF) have on B. bacteriovorus 109J transcriptomics. Bdellovibrio bacteriovorus 109J was exposed to DSF during both its attack, and intraperiplasmic growth phases, and its transcriptomics were compared to those cells which were not exposed.
