Members of the Enterobacteriaceae family produce a diffusible signal factor that modulates enteric pathogen virulence

ABSTRACT Diffusible signal factors (DSFs) are a gammaproteobacterial family of quorum-sensing signals that mediate the transition between sessile and planktonic lifestyles. In addition to coordinating behavior within producing species, DSFs can be sensed by surrounding organisms, enabling interspecies “eavesdropping.”...

Salmonella exploits a quorum-sensing family signal of the gut commensal Stenotrophomonas maltophilia to facilitate its colonization

It is shown that Salmonella-induced oxidative stress can stimulate the colonic resident Stenotrophomonas maltophilia to enhance the secretion of the diffusible signal factor cis-2-hexadecenoic acid (c2-HDA), a potent repressor of Salmonella virulence.
