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. Overall design: 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.
